stable inclusion from stable-5.10.50 commit 5091f2738d78a9267616d5740ebf70ce44bd4881 bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 8f2e452730d2bcd59fe05246f0e19a4c52e0012d ]
The media_device_usb_allocate() function returns error pointers when it's enabled and something goes wrong. It can return NULL as well, but only if CONFIG_MEDIA_CONTROLLER is disabled so that doesn't apply here.
