From 09fda3469d76280f162ee6bdb2fbfbe40f7c1e6f Mon Sep 17 00:00:00 2001 From: Dmitry Eremin-Solenikov Date: Thu, 5 Dec 2013 00:07:17 +0400 Subject: [PATCH 15/44] video: backlight: drop old locomo bl/lcd driver Old locomolcd driver is now completely obsolete by new locomo_bl and locomo_lcd drivers, so let's drop it.
