2014-04-08backlight: core: Replace kfree with put_deviceLevente Kurusa1-1/+1
As per the comments on device_register, we shouldn't call kfree() right after a device_register() failure. Instead call put_device(), which in turn will call bl_device_release resulting in a kfree to the full structure.

2014-04-03backlight: update backlight status when necessaryLiu Ying1-2/+3
We don't have to update a backlight status every time a blanking or unblanking event comes because the backlight status may have already been what we want. Another thought is that one backlight device may be shared by multiple framebuffers. We don't hope blanking one of the framebuffers may turn the backlight off for all the other framebuffers, since they are likely being active to display something. This patch makes the backlight status be updated only when the relevant backlight device's use count changes from zero to one or from one to zero.

2014-04-03backlight: update bd state & fb_blank properties when necessaryLiu Ying1-5/+18
We don't have to update the state and fb_blank properties of a backlight device every time a blanking or unblanking event comes because they may have already been what we want. Another thought is that one backlight device may be shared by multiple framebuffers. The backlight driver should take the backlight device as a resource shared by all the associated framebuffers. This patch adds some logic to record each framebuffer's backlight usage to determine the backlight device use count and whether the two properties should be updated or not. To be more specific, only one unblank operation on a certain blanked framebuffer may increase the backlight device's use count by one, while one blank operation on a certain unblanked framebuffer may decrease the use count by one, because the userspace is likely to unblank an unblanked framebuffer or blank a blanked framebuffer.

2014-01-30drivers/video/backlight/lcd.c: call put_device if device_register failsLevente Kurusa1-1/+1
Currently we kfree the container of the device which failed to register. This is wrong as the last reference is not given up with a put_device call. Also, now that we have put_device() callen, we no longer need the kfree as the new_ld->dev.release function will take care of kfreeing the associated memory.
