Subject: [PATCH 0/2] drm/msm/dpu: Minor virtual planes fixes

This series adds the following fixes related to the virtual planes code
changes:

1) Initialize the return value of dpu_assign_plane_resources() so that
   the function doesn't return a garbage value if all planes are
   disabled/otherwise not visible.
2) Remove extraneous return value for dpu_crtc_reassign_planes()

These were discovered when setting `msm.dpu_use_virtual_planes=1` in the
command line arguments, but not forcing virtual planes to be used.
