Follow-up on v4 - with only a few changes listed below and in the individual patches. Thanks for all the reviews and the feedback on the patches! I am planning a follow-up on this patchset to update the backlight drivers all over to use backlight_get_brightness() and backlight_is_blank() as appropriate. v5: - Added r-b's - Updated cr_bllcd to use gpio-backlight semantics - Various editorial updates to changelogs - Rebased on top of Lee's backlight tree - Dropped "make of_find_backlight_by_node() static" The change depends on drm-misc-next. Will be re-send when the changes hits the backlight tree (We could have done this in other ways, but it is easier to just wait) v4: - Introduced backlight_get_brightness based on feedback from Emil. - Properly described the rationale behind more restrictive locking use I checked that locking was not used outside backlight core by renaming the lock fields. As it is not used seems OK to restrict use to the core. - Introducing backlight_get_brightness invalidated some patches and I did a bit finer split to ease review. - Added acks - A few small adjustments documented in the individual patches v3: - Dropped video patch that was reviewd and thus applied - Updated kernel-doc so all fields now have a short intro - Improved readability in a lot of places, thanks to review feedback from Daniel - thanks! - Added better intro to backlight - Added acks Several other smaller changes documented in the patches. I left out patches to make functions static as there are dependencies to drm-misc-next for these. v2: - Dropped drm patches that was reviewed and thus applied (Thanks Tomi) - Updated backligth_is_blank() based on Daniel's feedback - Dropped EXPORT_SYMBOL that was no longer relevant - Reordered patches, so patches with no external dependencies comes first - Updated the description that follows. The following series touches a lot of backlight things. Starts with a small refactoring in backligth.c to remove some indents. This increases the readability and no functional changes. Then two new helpers backlight_is_blank(), backlight_get_brightness() are added. These helpers simplifies the implementation of update_status() in the backlight drivers where they are used. Then while surfing the code I missed some documentation. So I got a bit carried away and updated the documentation for the backlight core and added it to kernel-doc. The documentation express my current understanding. Everything from spelling errors to outright wrong content shall be anticipated - so please review! We are all best helped if the documentation is correct and up-to-date and it is readable. In this process I identified that the backlight_bl driver was no longer in use - so drop it. Everything builds, but so far no run-time testing.
