This patch replace actual mask stuff using BIT macros with or operators to make use of GENMASK macro which simplifies code clearity and readibility. It applies for defines included in p80211netdev.h header file. Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
