Subject: [PATCH v2 00/12] LED core improvements
This is a second version of the patch set preparing the
ground for removing work queues from LED class drivers.
Andrew and Sakari - thanks for a review.
================
Changes from v1:
================
- removed useless use of else in led_set_brightness()
- switched to removing error code instead of emitting
warning from led_set_brightness_sync() in case software
blink fallback is enabled
- moved __led_set_brightness() contents to set_brightness_delayed()
- removed description of internal led_set_brightness_nosleep() from
led-class.txt documentation, and modified description of
led_set_brightness() and led_set_brightness_sync()
- renamed LED_BLINK_CHANGE flag to more meaningful
LED_BLINK_BRIGHTNESS_CHANGE
- Fixed stylistic issues in a few comments
- Adopted old brightness_set_sync() op description to
a new brightness_set_blocking() op
- Fixed led_set_brightness_nosleep to avoid scheduling
spurious set_brightness_work
- made LED core using EXPORT_SYMBOL_GPL consistently
- switched v4l2-flash-led-class wrapper to using
led_set_brightness_sync API for setting torch brightness
- merged with patch set
"LED flash: Set brightness in a sync way on demand"
======================
Original cover letter:
======================
This patch set prepares the ground for removing work queues
from LED class drivers, and is a follow up of the patch set [1].
LED core modifications have been reorganized to make them
more clear and easier to review. The patch set is reduced
in comparison to it its predecessor, to expose the modifications
indispensable for the LED core to gain the capability of handling
brightness_set_blocking ops, that is without work queues.
Thanks,
Jacek Anaszewski
