In the Linux kernel, the following vulnerability has been resolved:drm/hisilicon/hibmc: fix the hibmc loaded failed bugWhen hibmc loaded failed, the driver use hibmc_unload to free theresource, but the mutexes in mode.config are not init, which willaccess an NULL pointer. Just change goto statement to return, becausehibnc_hw_init() doesn't need to free anything.
