X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bcd2ba02a41d46c426fd16ad530b96527a5f181a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm: Clarify the role of plane_state argument to drm_simple update(). Like the atomic update hook it's wrapping, the plane_state is the old one, and the new one is in plane->state. Both msxfb and tinydrm use it correctly, but I mistook it for the new state in pl111 due to its naming.
