From: Florian Tobias Schandinat Date: Sun, 12 Feb 2012 20:34:17 +0000 (+0000) Subject: viafb: LCD bpp cleanup X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=91dc1be8f698eb016343d534159a919678e3889c;p=mv-sheeva.git viafb: LCD bpp cleanup This patch removes redundant bits per pixel information by using the one storged in var directly. Simplifies code without any functional changes.
