Please rebase to current HEAD, I've just pushed there two ioctlent.sh
cleanup commits.

btw, there is a lookup regexp that could be used to handle drm/*drm.h,
linux/hsi/hsi_char.h, and linux/omapfb.h simultaneously:
^[[:space:]]*#[[:space:]]*define[[:space:]]\+\([A-Z][A-Z0-9_]*\)[[:space:]]\+\([A-Z]\+\)_\(IO\|IOW\|IOR\|IOWR\)[[:space:]]*(\([^,()]*\)[[:space:]]*[,)]
