Subject: [PATCH] drm/msm: Fix error return code in msm_drm_init()
Date: Tue, 17 Nov 2020 10:36:49 +0800 [thread overview]
Message-ID: <20201117023649.26657-1-liwei391@huawei.com> (raw)
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.
Fixes: 25fdd5933e4c ("drm/msm: Add SDM845 DPU support")
