2007-07-19USB: change name of spinlock in hcd.cAlan Stern
This patch (as940 renames hcd_data_lock in hcd.c to hcd_urb_list_lock, which is more descriptive of the lock's job. It also introduces a convenient inline routine for testing whether a particular USB device is a root hub.

2007-07-19USB: move routines in hcd.cAlan Stern
This patch (as939) moves a couple of routine in hcd.c around. The purpose is to put all the general URB- and endpoint-related routines (submit, unlink, giveback, and disable) together in one spot. There are no functional changes. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

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).

2007-07-19UHCI: short control URBs get a status stageAlan Stern

2007-07-19USB: mos7720, mos7840: remove redundant urb checkFlorin Malita
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>

a) switch by loff_t == __cmpdi2 use. Replaced with a couple of obvious ifs; update of ->f_pos in the first one makes sure that we do the right thing in all cases. b) block_signals() and unblock_signals() are globals on UML. Renamed coda ones; in principle UML probably ought to do rename as well, but that's another story.

2007-07-20ide: add support for SCSI ioctls to ide-floppyBartlomiej Zolnierkiewicz
Now that ide-floppy supports SG_IO we can add support for SCSI ioctls (except deprecated SCSI_IOCTL_SEND_COMMAND and legacy CDROM_SEND_PACKET ones - we can add them later iff really needed). While at it remove handling of CDROMEJECT and CDROMCLOSETRAY ioctls from generic_ide_ioctl(): - This prevents ide-{disk,tape,scsi} device drivers from obtaining REQ_TYPE_BLOCK_PC type requests which are currently unsupported by these drivers and which are potentially harmful (as reported by Andrew). - There is no functionality loss since aforementioned ioctls will now be handled by idefloppy_ioctl()->scsi_cmd_ioctl() (for devices using ide-floppy driver) and by idecd_ioctl->cdrom_ioctl()->scsi_cmd_ioctl() (for devices using ide-cd driver).
