Subject: [PATCH] drm/msm/dpu: Initialize return value for
dpu_assign_plane_resources()
Initialize the return value so that the dpu_crtc_atomic_check() doesn't
fail if the virtual planes command line parameter is enabled and no planes
are visible.
Fixes: 774bcfb73176 ("drm/msm/dpu: add support for virtual planes")
