2007-07-19USB: Remove pointless conditional in drivers/usb/serial/io_ti.c::edge_shutdown()Jesper Juhl
Coverity scan found (CID: 1708) this in drivers/usb/serial/io_ti.c::edge_shutdown() : ... 2797 for (i=0; i < serial->num_ports; ++i) { 2798 edge_port = usb_get_serial_port_data(serial->port[i]); 2799 edge_remove_sysfs_attrs(edge_port->port); 2800 if (edge_port) { 2801 edge_buf_free(edge_port->ep_out_buf); 2802 kfree(edge_port); 2803 } 2804 usb_set_serial_port_data(serial->port[i], NULL); 2805 } ... It's complaining that we dereference 'edge_port' in line 2799 which makes the test of that pointer against NULL in 2800 pointless, since if edge_port was actually NULL we'd have crashed already before reaching line 2800. Reading the edge_open() function it seems to me that the pointer returned by usb_get_serial_port_data(serial->port[i]) and stored in 'edge_port' can never actually be NULL here, so the test is entirely superfluous (even if it could be NULL it would be pointless here, ignoring the then possible crash in that case, since both edge_buf_free() and kfree() can handle being passed NULL pointers. This patch removes the pointless conditional (and also makes a few tiny style corrections now that I was in the area anyway).

Coverity (1709, 1710, 1711, 1712, 1713) actually flagged these as REVERSE_INULLs (NULL check performed after dereference). But looking at the other drivers I can't see any similar tests and the USB core already makes sure urb is non-null - so might as well get rid of the checks.

2007-07-19USB: fix warning caused by autosuspend counter going negativeAlan Stern
This patch (as937) fixes a minor bug in the autosuspend usage-counting code. Each hub's usage counter keeps track of the number of unsuspended children. However the current driver increments the counter after registering a new child, by which time the child may already have been suspended and caused the counter to go negative. The obvious solution is to increment the counter before registering the child.

2007-07-19USB: add "descriptors" binary sysfs attributeAlan Stern
This patch (as934) adds a new readonly binary sysfs attribute file called "descriptors" for each USB device. The attribute contains the device descriptor followed by the raw descriptor entry (config plug subsidiary descriptors) for the current configuration. Having this information available in fixed-format binary makes life a lot easier for user programs by avoiding the need to open, read, and parse multiple sysfs text files. The information in this attribute file is much like that in usbfs's device file, but there are some significant differences: The 2-byte fields in the device descriptor are left in little-endian byte order, as they appear on the bus and in the kernel. Only one raw descriptor set is presented, that of the current configuration. Opening this file will not cause a suspended device to be autoresumed. The last item in particular should be a big selling point for libusb, which currently forces all USB devices to be resumed as it scans the device tree.

2007-07-19isp116x-hcd: prepare for urb->statusAlan Stern
This patch (as931b), adapted from a patch by Olav Kongas, makes a small set of conservative changes to the isp116x-hcd driver in preparation for the removal of urb->status. finish_request() is moved up in the source and is called as soon as the URB is known to have completed, rather than after all the active endpoints have been scanned. The status of a completed URB is kept in a local variable and copied to urb->status only when the URB is about to be given back. -EREMOTEIO error status for control transfers is set after the status stage rather than when the short packet arrives. Some unnecessary uses of urb->lock are removed. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Cc: Olav Kongas <ok@artecdesign.ee> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-07-19USB: usblp: "Big cleanup" breaks O_NONBLOCKPete Zaitcev
I found the first regresson in the rewritten ("all dynamic" and "no races") driver. If application uses O_NONBLOCK, I return -EAGAIN despite the URB being submitted successfuly. This causes the application to resubmit the same data erroneously. The fix is to pretend that the transfer has succeeded even if URB was merely queued. It is the same behaviour as with the old version. Signed-off-by: Pete Zaitcev <zaitcev@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-07-18dev_vdbg(), available with -DVERBOSE_DEBUGDavid Brownell
This defines a dev_vdbg() call, which is enabled with -DVERBOSE_DEBUG. When enabled, dev_vdbg() acts just like dev_dbg(). When disabled, it is a NOP ... just like dev_dbg() without -DDEBUG. The specific code was moved out of a USB patch, but lots of drivers have similar support. That is, code can now be written to use an additional level of debug output, selected at compile time. Many driver authors have found this idiom to be very useful. A typical usage model is for "normal" debug messages to focus on fault paths and not be very "chatty", so that those messages can be left on during normal operation without much of a performance or syslog load. On the other hand "verbose" messages would be noisy enough that they wouldn't normally be enabled; they might even affect timings enough to change system or driver behavior.

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

Although the other USB driver directories got taught how use Kconfig and the Makefile to enable the debugging messages enabled by -DDEBUG, the gadget stack was overlooked.

2007-07-12usb gadget stack: remove usb_ep_*_buffer(), part 2David Brownell
This patch removes controller driver infrastructure which supported the now-removed usb_ep_{alloc,free}_buffer() calls. As can be seen, many of the implementations of this were broken to various degrees. Many didn't properly return dma-coherent mappings; those which did so were necessarily ugly because of bogosity in the underlying dma_free_coherent() calls ... which on many platforms can't be called from the same contexts (notably in_irq) from which their dma_alloc_coherent() sibling can be called. The main potential downside of removing this is that gadget drivers wouldn't have specific knowledge that the controller drivers have: endpoints that aren't dma-capable don't need any dma mappings at all.

2007-07-12usb gadget stack: remove usb_ep_*_buffer(), part 1David Brownell
Remove usb_ep_{alloc,free}_buffer() calls, for small dma-coherent buffers. This patch just removes the interface and its users; later patches will remove controller driver support. - This interface is invariably not implemented correctly in the controller drivers (e.g. using dma pools, a mechanism which post-dates the interface by several years). - At this point no gadget driver really *needs* to use it. In current kernels, any driver that needs such a mechanism could allocate a dma pool themselves. Removing this interface is thus a simplification and improvement.

Cleanups to the pxa2xx_udc code: - Primarily removing unused DMA hooks. - One "sparse" warning removed - Remove some Lubbock-only LED hooks (for debugging) That DMA code was never really completed. It worked, mostly, for IN transfers (to the host) if they were fortuitously aligned, but that code was never fully tested. And it was never coded for OUT transfers (which is where DMA would really help) ... because of chip errata on essentially every chip other than the pxa255, and because of design botches (nothing automated data toggle).

2007-07-12USB: usb/dma doc updatesDavid Brownell
This patch updates some of the documentation about DMA buffer management for USB, and ways to avoid extra copying. Our understanding of the issues has improved over time. - Most drivers should *avoid* the dma-coherent allocators. There are a few exceptions (like the HID driver). - Some methods are currently commented out; it seems folk writing USB drivers aren't doing performance tuning at that level yet. - Just avoid highmem; there's no good way to pass an "I can do highmem DMA" capability through a driver stack. This is easy, everything already avoids highmem. But it'd be nice if x86_32 systems with much physical memory could use it directly with network adapters and mass storage devices. (Patch, anyone?)
