Include appropriate header file include/drm/drm_usb.h in drm/drm_usb.c because functions drm_get_usb_dev(), drm_usb_init() and drm_usb_exit() have their prototype declarations in the header file.
This eliminates the following warning in drm/drm_usb.c: drivers/gpu/drm/drm_usb.c:5:5: warning: no previous prototype for ?drm_get_usb_dev? [-Wmissing-prototypes] drivers/gpu/drm/drm_usb.c:61:5: warning: no previous prototype for ?drm_usb_init? [-Wmissing-prototypes] drivers/gpu/drm/drm_usb.c:75:6: warning: no previous prototype for ?drm_usb_exit?
