In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Fix pdev reference leak in mtkdrmbind()
When the device is not the mmsys master, mtkdrmbind() returns early after taking a reference on the disp-mutex device via offinddevicebynode(), without ever dropping it: mtkdrmunbind() only puts mutexdev for the master. Drop the reference before returning from the non-master path.
