| |
The pwc driver causes a warning when CONFIG_USB_PWC_INPUT_EVDEV is unset:
drivers/media/usb/pwc/pwc-if.c: In function 'usb_pwc_probe': drivers/media/usb/pwc/pwc-if.c:1115:1: warning: label 'err_video_unreg' defined but not used [-Wunused-label]
Obviously, the cleanup of &pdev->vdev is not needed without the input device, so we can just move it inside of the existing #ifdef and remove the extra label.
