From ce481edad41098b535c15661e2e47a0934a24a7a Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 19 Apr 2016 09:06:32 +0300 Subject: drm/omap: fix pitch round-up At the moment we calculate the buffer's pitch with: pitch = width * DIV_ROUND_UP(bpp, 8) For CLUT modes with bpp of 1/2/4/8 this gives wrong result, and the correct pitch is: pitch = DIV_ROUND_UP(width * bpp, 8) In practice this doesn't change anything, as we don't support CLUT modes, but it's better to have the pitch calculation correct.
