Subject: [PATCH v2 28/33] drm/msm/dpu: drop ununused PINGPONG features
From: Dmitry Baryshkov <lumag@...nel.org>
The DPU_PINGPONG_TE2 is unused by the current code (and can further be
replaced by the checking for the te2 sblk presense). Other feature bits
are completely unused. Drop them from the current codebase.
