2011-03-22pwm_backlight: add check_fb() hookRobert Morell
In systems with multiple framebuffer devices, one of the devices might be blanked while another is unblanked. In order for the backlight blanking logic to know whether to turn off the backlight for a particular framebuffer's blanking notification, it needs to be able to check if a given framebuffer device corresponds to the backlight. This plumbs the check_fb hook from core backlight through the pwm_backlight helper to allow platform code to plug in a check_fb hook.

The reset command is part of the init sequence and it take effect only if the lcd is powered. The effect of the bug was that the sequence: set lcd power_state to FB_BLANK_POWERDOWN set lcd power_state to FB_BLANK_UNBLANK Did not produced a complete reboot of the LCD which was showing fuzzy colours. This was not experienced before implementing correctly all the LCD power states with the patch [1]. Since before the patch [1] the regulators were not touched and the LCD shutdown was reached with a register write. After the patch [1] a complete boot sequence with an initial reset is needed for the display every time the LCD is powered up. drivers-video-backlight-l4f00242t03c-full-implement-fb-power-states-for-this-lcd.patch Signed-off-by: Alberto Panizzo <maramaopercheseimorto@gmail.com> Cc: Richard Purdie <rpurdie@rpsys.net> Cc: Marek Vasut <marek.vasut@gmail.com> Cc: Tejun Heo <tj@kernel.org> Cc: Axel Lin <axel.lin@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2010-11-25backlight: grab ops_lock before testing bd->opsUwe Kleine-König
According to the comment describing ops_lock in the definition of struct backlight_device and when comparing with other functions in backlight.c the mutex must be hold when checking ops to be non-NULL. Fixes a problem added by c835ee7f4154992e6 ("backlight: Add suspend/resume support to the backlight core") in Jan 2009.

2010-11-16backlight: constify backlight_opsLionel Debroux
backlight_device_register has been expecting a const "ops" argument, and using it as such, since 9905a43b2d563e6f89e4c63c4278ada03f2ebb14. Let's make the remaining backlight_ops instances const. Inspired by hunks of the grsecurity patch, updated for newer kernels.
