| |
atomisp_mrfld_power() has no more callers and produces a warning:
drivers/staging/media/atomisp/pci/atomisp_v4l2.c:764:12: error: unused function 'atomisp_mrfld_power' [-Werror,-Wunused-function]
Mark the function as unused while the PM code is being debugged, expecting that it will be used again in the future and should not just be removed.
