* leds: leds-gpio: Use platform_{get,set}_drvdataTobias Klauser2012-09-111-2/+2

* leds: leds-gpio: use of_match_ptr()Tobias Klauser2012-09-111-2/+1Star
| | | | | | | | Instead of having to define the match table to NULL if CONFIG_OF isn't set, use the of_match_ptr() macro which will do this for us. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
* leds: delay led_set_brightness if stopping soft-blinkFabio Baltieri2012-09-114-4/+33
| | | | | | | | | | | | Delay execution of led_set_brightness() if need to stop soft-blink timer. This allows led_set_brightness to be called in hard-irq context even if soft-blink was activated on that LED.

* leds: renesas: fix error handlingArnd Bergmann2012-08-131-1/+1
| | | | | | | | | | | | | | | | | bfe4c041 "leds: convert Renesas TPU LED driver to devm_kzalloc() and cleanup error exit path" introduced a possible case in which r_tpu_probe calls iounmap on a wild pointer. This changes the one case that was missed in the same way as the other error paths. Without this patch, building kota2_defconfig results in: drivers/leds/leds-renesas-tpu.c: In function 'r_tpu_probe': drivers/leds/leds-renesas-tpu.c:246:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] drivers/leds/leds-renesas-tpu.c:308:17: warning: 'p' may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Magnus Damm <damm@opensource.se> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>

| | | | | | | | | | | This reverts commit a0193cbee0809d65362a0767b2d50306b145b2f5. The problem with the original commit was that it caused a warning with the MMC trigger calling del_timer_sync from hard-irq context.

* leds: add new lp8788 led driverKim, Milo2012-07-263-0/+200
| | | | | | | | | | | | | | | | | | | | | | | | TI LP8788 PMU has the current sink as the keyboard led driver. The brightness is controlled by the i2c commands. Configurable parameters can be defined in the platform side. Patch v2. (a) use workqueue on changing the brightness (b) use mutex_lock/unlock when the brightness is set and the led block of lp8788 device is enabled (c) remove err_dev on _probe() : just return as returned value if any errors (d) replace module_init/exit() with module_platform_driver() (e) add led configuration structure and loading them by default if platform data is null Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>

* leds-lp5523: BUG() in error handling in probe()Dan Carpenter2012-07-241-3/+3
| | | | | | | | | | | | | | | | | | | Inside the error handling in lp5523_init_led(), there is a place that calls to led_classdev_unregister(). When we unregister the LED drivers, it tries to set the brightness to OFF. In this driver setting the brightness is done through a work queue and the work queue hasn't been initialized yet. The result is that we trigger a WARN_ON() in the __queue_work(). The fix is to move the INIT_WORK() in front of the call to lp5523_init_led(). Matt Renzelmann found this using a bug finding tool.
