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