[PATCH v2 05/14] drm/msm/dpu: handle pipes as array
Posted by Jun Nie 1 month, 2 weeks ago
Store pipes in array with removing dedicated r_pipe. There are
2 pipes in a drm plane at most currently. While 4 pipes are
needed for new usage case. This change generalize the handling
to pipe pair and ease handling to another pipe pair later.

Yes, the loop is missed. Will add it.

No need actually. It is a typo when converting type of many i.

be if (i == 1) or if (i > 0), which means a typo in my review comment.
