2019-02-16Input: qt2160 - remove redundant spinlockSven Van Asbroeck1-9/+0
Remove a spinlock which prevents schedule_delayed_work() and mod_delayed_work() from executing concurrently. This was required back when mod_delayed_work() did not exist, and had to be implemented with a cancel + schedule. See commit e7c2f967445d ("workqueue: use mod_delayed_work() instead of __cancel + queue") schedule_delayed_work() and mod_delayed_work() can now be used concurrently. So the spinlock is no longer needed. Signed-off-by: Sven Van Asbroeck <TheSven73@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2019-02-11Input: qt2160 - switch to using brightness_set_blocking()Dmitry Torokhov1-42/+27
Now that LEDs core allows "blocking" flavor of "set brightness" method we can use it and get rid of private work items. Reviewed-by: Sven Van Asbroeck <TheSven73@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2015-07-17Input: drop owner assignment from i2c_driverKrzysztof Kozlowski1-1/+0
i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2014-01-06Input: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-01-04Input: qt2160 - add support for LEDsJavier Martin1-2/+139
Outputs x8..x0 of the qt2160 can have leds attached to it. This patch handles those outputs using the generic LED framework. The PWM controls available in the chip are used to achieve different levels of brightness.

2012-10-25Input: qt2160 - fix qt2160_write() implementationJavier Martin1-14/+5
The previous implementation of qt2160_write() didn't work properly because the value was actually not written to the device. Probably nobody detected this because the only write that was issued was the one related to auto calibration. In order to fix the problem use a similar aproach as qt1070 instead.

2012-08-21workqueue: use mod_delayed_work() instead of __cancel + queueTejun Heo1-2/+1
Now that mod_delayed_work() is safe to call from IRQ handlers, __cancel_delayed_work() followed by queue_delayed_work() can be replaced with mod_delayed_work(). Most conversions are straight-forward except for the following. * net/core/link_watch.c: linkwatch_schedule_work() was doing a quite elaborate dancing around its delayed_work. Collapse it such that linkwatch_work is queued for immediate execution if LW_URGENT and existing timer is kept otherwise. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.

2012-03-16Input: convert I2C drivers to use module_i2c_driver()Axel Lin1-11/+1

2010-06-03i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang1-1/+0
I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.
