[PATCH v2] drm/tegra: plane: Keep 'dependent' blending state of unaffected planes

From: Dmitry Osipenko
Date: Thu Mar 15 2018 - 10:26:03 EST


This way new state takes into account the current state of unaffected
(by the atomic commit) planes.

v2: Dropped unrelated 'cleanup' changes and fixed
s/state->dependent[i]/state->dependent[index]/ typo.
