Subject: [PATCH 02/11] OMAPDSS: ls037v7dw01: remove platform backlight calls
Date: Wed, 13 Feb 2013 14:19:05 +0000 [thread overview]
Message-ID: <1360764434-18788-3-git-send-email-archit@ti.com> (raw)
In-Reply-To: <1360764434-18788-1-git-send-email-archit@ti.com>
From: Tomi Valkeinen <tomi.valkeinen@ti.com>
Sharp ls037v7dw01 driver contains support to call platform backlight
functions. These are not used by any board, and can be removed.
