#     atomisp: avoid warning about unused function
#     
#     The atomisp_mrfld_power() function isn't actually ever called, because
#     the two call-sites have commented out the use because it breaks on some
#     platforms.  That results in:
#     
#       drivers/staging/media/atomisp/pci/atomisp_v4l2.c:764:12: warning: ‘atomisp_mrfld_power’ defined but not used [-Wunused-function]
#         764 | static int atomisp_mrfld_power(struct atomisp_device *isp, bool enable)
#             |            ^~~~~~~~~~~~~~~~~~~
#     
#     during the build.
#     
#     Rather than commenting out the use entirely, just disable it
#     semantically instead (using a "0 &&" construct), leaving the call in
#     place from a syntax standpoint, and avoiding the warning.
#     
#     I really don't want my builds to have any warnings that can then hide
#     real issues.
