[PATCH 0/1] drm/blend: size zpos array to active planes instead of total

[Gustavo Piaz Da Silva]

drm_atomic_helper_crtc_normalize_zpos() allocates a temporary
array sized by dev->mode_config.num_total_plane, which counts
all planes registered on the device. The function only operates
on planes active on the given CRTC, as described by
crtc_state->plane_mask.

Replace num_total_plane with hweight32(crtc_state->plane_mask)
to size the allocation to exactly the planes being processed.
