Subject: [PATCH 5.13 550/800] drm/msm: Fix error return code in msm_drm_init()
From: Zhen Lei <thunder.leizhen@...wei.com>
[ Upstream commit a1c9b1e3bdd6d8dc43c18699772fb6cf4497d45a ]
Fix to return a negative error code from the error handling case instead
of 0, as done elsewhere in this function.
Fixes: 7f9743abaa79 ("drm/msm: validate display and event threads")
