drm/i915: correct the pitch check for NV12 framebuffer

RavirajSitaram · vsyrjala · commit 29214e8cf6ce · 2019-01-25T23:31:24.000+02:00
framebuffer for NV12 requires the pitch to the multiplier of 4, instead of the width. This patch corrects it. For instance, a 480p video, whose width and pitch are 854 and 896 respectively, is excluded for NV12 plane so far. Changes since v1: - Removed check for NV12 buffer dimensions since additional checks are done for viewport size in intel_sprite.c Signed-off-by: Dongseong Hwang <dongseong.hwang@intel.com> Signed-off-by: P Raviraj Sitaram <raviraj.p.sitaram@intel.com> Cc: Chandra Konduru <chandra.konduru@intel.com> Cc: Vidya Srinivas <vidya.srinivas@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1545208152-22658-1-git-send-email-raviraj.p.sitaram@intel.com
