[PATCH] airo: simpler calling convention for enable_MAC()
Callers of enable_MAC() shouldn't have to worry about the bits in the response's status word (and most of them don't). The return value is sufficient information. Signed-off-by: Michal Schmidt <mschmidt@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
