As of commit 57e6b6f2303e ("media: atomisp_fops.c: disable atomisp_compat_ioctl32"), nothing in this file is actually getting used as the only reference has been stubbed out. Do the same thing here and stub out the implementation as well while leaving it in place, with a comment explaining the problem. Alternatively, the entire file could just be removed, since anyone willing to restore the functionality can equally well just look up the contents in the git history if needed.
