• cbe99c538   leds: ktd2692: avoid harmless maybe-uninitialized warning ... Browse Code »

  gcc gets confused about the control flow in ktd2692_parse_dt(), causing
  it to warn about what seems like a potential bug:

  drivers/leds/leds-ktd2692.c: In function 'ktd2692_probe':
  drivers/leds/leds-ktd2692.c:244:15: error: '*((void *)&led_cfg+8)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  drivers/leds/leds-ktd2692.c:225:7: error: 'led_cfg.flash_max_microamp' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  drivers/leds/leds-ktd2692.c:232:3: error: 'led_cfg.movie_max_microamp' may be used uninitialized in this function [-Werror=maybe-uninitialized]

  The code is fine, and slightly reworking it in an equivalent way lets
  gcc figure that out too, which gets rid of the warning.

• 77e7915b1   leds: ktd2692: Add missing of_node_put ... Browse Code »

  The refcount of device_node increases after of_node_get() is called.
  So, a break out of the loop requires of_node_put().

  This patch adds missing of_node_put() when loop breaks.

• 437a4240f   leds: Rename brightness_set_sync op to brightness_set_blocking ... Browse Code »

  The initial purpose of brightness_set_sync op, introduced along with
  the LED flash class extension, was to add a means for setting torch LED
  brightness as soon as possible, which couldn't have been guaranteed by
  brightness_set op. This patch renames the op to brightness_set_blocking,
  which describes its purpose in a more generic way. It is beneficial
  in view of the prospective changes in the LED core, aiming at removing
  the need for using work queues in LED class drivers that can sleep
  or use delays while setting brightness.

  Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
  which appeared in v3.17-rc1, the gpiod_get* functions take an additional
  parameter that allows to specify direction and initial value for output.

  In this case the driver cannot easily be simplified but as the flags
  parameter will become mandatory soon this change is necessary
  beforehand.
