Subject: [PATCH] ARM: AMBA CLCD: X resolutions must be multiples of 16
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=0f7ad450394560a6b6c72115e04bf7afd6230e70;p=deliverable%2Flinux.git

[PATCH] ARM: AMBA CLCD: X resolutions must be multiples of 16

We ignore the bottom 4 bits of the X resolution, so we should
round X resolutions up to the nearest multiple of 16.
