The patch titled
drivers/video/backlight: rename da903x to da903x_bl
has been removed from the -mm tree. Its filename was
drivers-video-backlight-rename-da903x-to-da903x_bl.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: drivers/video/backlight: rename da903x to da903x_bl
From: Mike Rapoport <mike@xxxxxxxxxxxxxx>
Currently both da903x backlight and voltage reulator drivers have the
same name. Rename the backlight driver to allow use of both drivers as
modules.
