2010-10-05drivers: autoconvert trivial BKL users to private mutexArnd Bergmann
All these files use the big kernel lock in a trivial way to serialize their private file operations, typically resulting from an earlier semi-automatic pushdown from VFS. None of these drivers appears to want to lock against other code, and they all use the BKL as the top-level lock in their file operations, meaning that there is no lock-order inversion problem. Consequently, we can remove the BKL completely, replacing it with a per-file mutex in every case. Using a scripted approach means we can avoid typos. These drivers do not seem to be under active maintainance from my brief investigation. Apologies to those maintainers that I have missed. file=$1 name=$2 if grep -q lock_kernel ${file} ; then if grep -q 'include.*linux.mutex.h' ${file} ; then sed -i '/include.*<linux\/smp_lock.h>/d' ${file} else sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file} fi sed -i ${file} \ -e "/^#include.*linux.mutex.h/,$ { 1,/^\(static\|int\|long\)/ { /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex); } }" \ -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \ -e '/[ ]*cycle_kernel_lock();/d' else sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \ -e '/cycle_kernel_lock()/d' fi Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The fix is to call usb_autopm_get_interface() first, before we take the lock. Since we do not do usb_autopm_put_interface() until wacom_close() is called runtime PM is effectively disabled for the driver, however changing it now would risk regressions so the complete fix will have to wait till the next merge window.

2010-09-09Input: add support for large scancodesMauro Carvalho Chehab
Several devices use a high number of bits for scancodes. One important group is the Remote Controllers. Some new protocols like RC-6 define a scancode space of 64 bits. The current EVIO[CS]GKEYCODE ioctls allow replace the scancode/keycode translation tables, but it is limited to up to 32 bits for scancode. Also, if userspace wants to clean the existing table, replacing it by a new one, it needs to run a loop calling the ioctls over the entire sparse scancode space. To solve those problems, this patch extends the ioctls to allow drivers handle scancodes up to 32 bytes long (the length could be extended in the future should such need arise) and allow userspace to query and set scancode to keycode mappings not only by scancode but also by index. Compatibility code were also added to handle the old format of EVIO[CS]GKEYCODE ioctls. Folded fixes by: - Dan Carpenter: locking fixes for the original implementation - Jarod Wilson: fix crash when setting keycode and wiring up get/set handlers in original implementation. - Dmitry Torokhov: rework to consolidate old and new scancode handling, provide options to act either by index or scancode.

2010-09-05Input: wacom - add a quirk for low resolution Bamboo devicesHenrik Rydberg
The Bamboo Touch reports a sub-screen resolution of 480x320. The signal-to-noise ratio is only about 100, so filtering is needed in order to reduce the jitter to a usable level. However, the low resolution leads to round-off errors in the EWMA filter, resulting in extremely jerky pointer motion. This patch explicitly sets a higher resolution for those devices, and tells this to the completion handler via a low-resolution quirk.
