Subject: [PATCH 5.14 183/334] drm/msm: Fix error return code in msm_drm_init()

From: Wei Li <liwei391@...wei.com>

[ Upstream commit bfddcfe155a2fe448fee0169c5cbc82c7fa73491 ]

When it fail to create crtc_event kthread, it just jump to err_msm_uninit,
while the 'ret' is not updated. So assign the return code before that.
