[PATCH -next] media: staging: stkwebcam: Fix the build error with stkwebcam

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When I am building the kernel on arm64, set config CONFIG_USB=m &&
CONFIG_VIDEO_STKWEBCAM=y, I get some error reports as follows:
  drivers/staging/media/deprecated/stkwebcam/stk-webcam.o: In
    function `stk_v4l_dev_release':
  stk-webcam.c:(.text+0x3e0): undefined reference to `usb_put_intf'
  stk-webcam.c:(.text+0x3e8): undefined reference to `usb_put_dev'
  drivers/staging/media/deprecated/stkwebcam/stk-webcam.o: In
  function `stk_clean_iso':
  stk-webcam.c:(.text+0xb0c): undefined reference to `usb_kill_urb'
  stk-webcam.c:(.text+0xb14): undefined reference to `usb_free_urb'

Fix it by add dependency option on USB for VIDEO_STKWEBCAM.
