[ 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.
Fixes: 812658d88d26 ("media: change au0828 to use Media Device Allocator API")
