* Input: pmic8xxx-pwrkey - migrate to regmap APIsStephen Boyd2013-12-151-4/+11
| | | | | | | | | Use the regmap APIs for this driver instead of custom pm8xxx APIs. This breaks this driver's dependency on the pm8xxx APIs and allows us to easily port it to other bus protocols in the future.

* Input: cyttsp - include appropriate header file in cyttsp_i2c_common.cRashika Kheria2013-12-151-0/+2
| | | | | | | | | | | | | | Include cyttsp4_core.h in cyttsp_i2c_common.c to ensure that implementation of cyttsp_i2c_read_block_data() and cyttsp_i2c_write_block_data() match what the rest of the driver expects. Thus, it also eliminates the following warning in cyttsp_i2c_common.c: drivers/input/touchscreen/cyttsp_i2c_common.c:34:5: warning: no previous prototype for ‘cyttsp_i2c_read_block_data’ [-Wmissing-prototypes] drivers/input/touchscreen/cyttsp_i2c_common.c:64:5: warning: no previous prototype for ‘cyttsp_i2c_write_block_data’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

* Input: allow deselecting serio drivers even without CONFIG_EXPERTTom Gundersen2013-10-312-5/+5
| | | | | | | | | | | | | | | | | There is plenty of consumer hardware (e.g., mac books) that does not use AT keyboards or PS/2 mice. It therefore makes sense for distro kernels to build the related drivers as modules to avoid loading them on hardware that does not need them. As such, these options should no longer be protected by EXPERT. Moreover, building these drivers as modules gets rid of the following ugly error during boot: [ 2.337745] i8042: PNP: No PS/2 controller found. Probing ports directly.

* Input: evdev - fall back to vmalloc for client event bufferDaniel Stone2013-10-311-4/+12
| | | | | | | | | | | | | | | evdev always tries to allocate the event buffer for clients using kzalloc rather than vmalloc, presumably to avoid mapping overhead where possible. However, drivers like bcm5974, which claims support for reporting 16 fingers simultaneously, can have an extraordinarily large buffer. The resultant contiguous order-4 allocation attempt fails due to fragmentation, and the device is thus unusable until reboot. Try kzalloc if we can to avoid the mapping overhead, but if that fails, fall back to vzalloc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch bumps the default number of tags allocated per session by iscsi-target via transport_alloc_session_tags() -> percpu_ida_init() by another (tag_num / 2). This is done to take into account the tags waiting to be acknowledged and released in iscsit_ack_from_expstatsn(), but who's number are not directly limited by the CmdSN Window queue_depth being enforced by the target. Using a larger value here is also useful to prevent percpu_ida_alloc() from having to steal tags from other CPUs when no tags are available on the local CPU, while waiting for unacknowledged tags to be released.
