# NOTE:
# Compiling this driver produces some warnings (and some more are
# switched off below), but I did not fix this, because the Hardware
# Module source (see skfddi.c for details) is used for different
# drivers, and fixing it for Linux might bring problems on other
# projects. To keep the source common for all those drivers (and
# thus simplify fixes to it), please do not clean it up!
