2009-04-04thinkpad-acpi: cleanup debug helpersHenrique de Moraes Holschuh
Fix the vdbg_printk macro definition to be sane when CONFIG_THINKPAD_ACPI_DEBUG is undefined, and move the mess into a file section of its own. This doesn't change anything in the current code, but future code will need the proper behaviour.

2009-04-03tc1100-wmi: Fix state reportingKrzysztof Kosiński
The tc1100-wmi driver should print the current states of wireless LAN and jogdial brightness control when "cat /sys/devices/platform/tc1100-wmi/wireless" and "cat /sys/devices/platform/tc1100-wmi/jogdial" are executed, respectively. What actually happens is that both of those commands print 0 regardless of the hardware state. The cause is that wmi_query_block returns an ACPI_TYPE_INTEGER rather than ACPI_TYPE_BUFFER as the driver assumes. Additionally, the driver intends to return a jogdial state that is inverted with respect to the commands required to set it (e.g. it intends to return 1 after the jogdial file was written with 0). This patch fixes both of those issues - the commands to query the state now work, and should return the same state that was written. http://bugzilla.kernel.org/show_bug.cgi?id=12286 Signed-off-by: Krzysztof Kosiński <tweenk.pl@gmail.com> Acked-by: Carlos Corbacho <carlos@strangeworlds.co.uk> Signed-off-by: Len Brown <len.brown@intel.com>

2009-03-31proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan
Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

2009-03-16Rationalize fasync return valuesJonathan Corbet
Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.

2009-03-16thinkpad-acpi: fix module autoloading for older modelsMathieu Chouquet-Stringer
Looking at the source, there seems to be a missing * to match my DMI string. I mean for newer IBM and Lenovo's laptops you match either one of the following: MODULE_ALIAS("dmi:bvnIBM:*:svnIBM:*:pvrThinkPad*:rvnIBM:*"); MODULE_ALIAS("dmi:bvnLENOVO:*:svnLENOVO:*:pvrThinkPad*:rvnLENOVO:*"); While for older Thinkpads, you do this (for instance): IBM_BIOS_MODULE_ALIAS("1[0,3,6,8,A-G,I,K,M-P,S,T]"); with IBM_BIOS_MODULE_ALIAS being MODULE_ALIAS("dmi:bvnIBM:bvr" __type "ET??WW") Note there's no * terminating the string. As result, udev doesn't load anything because modprobe cannot find anything matching this (my machine actually): udevtest: run: '/sbin/modprobe dmi:bvnIBM:bvr1IET71WW(2.10):bd06/16/2006:svnIBM:pn236621U:pvrNotAv Signed-off-by: Mathieu Chouquet-Stringer <mchouque@free.fr> Acked-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Len Brown <len.brown@intel.com>

Currently we disable the Acer WMI backlight device if there is no ACPI backlight device. As a result, we end up with no backlight device at all. We should instead disable it if there is an ACPI device, as the other laptop drivers do. This regression was introduced in febf2d9 ("Acer-WMI: fingers off backlight if video.ko is serving this functionality"). Each laptop driver with backlight support got a similar change around febf2d9. The changes to the other drivers look correct; see e.g. a598c82f for a similar but correct change. The regression is also in 2.6.28.

2009-02-21fujitsu-laptop: Use RFKILL support bitmask from firmwareTony Vroon
Up until now, we polled the rfkill status for every incoming FUJ02E3 ACPI event. It turns out that the firmware has a bitmask which indicates what rfkill-related state it can report. The rfkill_supported bitmask is now used to avoid polling for rfkill at all in the notification handler if there is no support. Also, it is used in the platform device callbacks. As before we register all callbacks and report "unknown" if the firmware does not give us status updates for that particular bit. This was fed through checkpatch.pl and tested on the S6420, S7020 and P8010 platforms.

eeepc-laptop init I got the following oops while changing the backlight brightness during startup. When it happens, it prevents use of the hotkeys, Fn-Fx, and the lid button. It's a clear use-before-init, as I verified by testing with an appropriately-placed "else printk".

2009-02-05hp-wmi: fix error path in hp_wmi_bios_setup()Andrew Morton
The error-path code can call rfkill_unregister() with a pointer which does not contain the result of a call to rfkill_register(). It goes BUG().
