| * HID: microsoft: do not use compound literal - fix buildJiri Slaby2012-11-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In patch "HID: microsoft: fix invalid rdesc for 3k kbd" I fixed support for MS 3k keyboards. However the added check using memcmp and a compound statement breaks build on architectures where memcmp is a macro with parameters. hid-microsoft.c:51:18: error: macro "memcmp" passed 6 arguments, but takes just 3 On x86_64, memcmp is a function, so I did not see the error.

| * HID: hidraw: put old deallocation mechanism in placeJiri Kosina2012-11-011-26/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This basically reverts commit 4fe9f8e203fda. It causes multiple problems, namely: - after rmmod/modprobe cycle of bus driver, the input is not claimed any more. This is likely because of misplaced hid_hw_close() - it causes memory corruption on hidraw_list As original patch author is not responding to requests to fix his patch, and the original deallocation mechanism is not exposing any problems, I am reverting back to it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Microsoft Digital Media Keyboard 3000 has two interfaces, and the second one has a report descriptor with a bug. The second collection says: 05 01 -- global; usage page -- 01 -- Generic Desktop Controls 09 80 -- local; usage -- 80 -- System Control a1 01 -- main; collection -- 01 -- application 85 03 -- global; report ID -- 03 19 00 -- local; Usage Minimum -- 00 29 ff -- local; Usage Maximum -- ff 15 00 -- global; Logical Minimum -- 0 26 ff 00 -- global; Logical Maximum -- ff 81 00 -- main; input c0 -- main; End Collection I.e. it makes us think that there are all kinds of usages of system control. That the keyboard is a not only a keyboard, but also a joystick, mouse, gamepad, keypad, etc. The same as for the Wireless Desktop Receiver, this should be Physical Min/Max. So fix that appropriately.

A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...

This patch uses a temporary buffer to shield dev_rdesc from the side effects of many HID drivers' report_fixup implementations. usbhid's hid_post_reset checks the report descriptor currently returned by the device against a descriptor that may have been modified by a driver's report_fixup method. That leaves some devices nonfunctional after a resume, with a "reset_resume error 1" reported. This patch checks the new descriptor against the unmodified dev_rdesc instead and uses the original, instead of modified, report size.

However when generic HID code has been converted to bus and individual quirks separated out to individual drivers on the bus, the copyright has been blindly transfered into all the tiny drivers, which actually don't contain any of Pauls' copyrighted code. Remove the copyright from those sub-drivers. Signed-off-by: Jiri Kosina <jkosina@suse.cz> Acked-by: Paul Walmsley <paul@pwsan.com>
| * | | | HID: Remove "default m" from HID_LOGITECH_DJJosh Triplett2012-09-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HID_LOGITECH_DJ uses "default m", which enables it in default kernel builds. Since this module just enables extra, non-critical functionality for one particular piece of hardware (specifically, differentiating multiple wireless keyboards and mice as separate input devices rather than treating them as one device), and the hardware works just fine with the default USB HID support, drop the "default m".

| * | | | | HID: Bump maximum global item tag report size to 128 bytesMarek Vasut2012-08-151-1/+1

Linux checks if this is 96 as of now, see [1]. This causes Linux to refuse to communicate with this device, making it impossible to use the recovery mode. This is not a standard HID device per se, but rather a software emulation implemented within the BootROM code and realized through USB OTG-capable port switched to device mode present on the device. Previous attempt to discuss this issue dates back to 2011, see [2]. There has been not much response. Also noteworthy is the [3], where there seems to be a pointing device that has issue similar to this one. The tool making use of the USB recovery mode is available at [4].
