From: Baihan Li <libai...@huawei.com>
When hibmc loaded failed, the driver use hibmc_unload to free the
resource, but the mutexes in mode.config are not init, which will
access an NULL pointer. Just change goto statement to return, because
hibnc_hw_init() doesn't need to free anything.
Fixes: b3df5e65cc03 ("drm/hibmc: Drop drm_vblank_cleanup")
