[PATCH 1/4] staging: wlan-ng: use GENMASK macro in different defines of hfa384x.h

From: Sergio Paracuellos
Date: Thu Nov 10 2016 - 13:17:10 EST


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 hfa384x.h header file.
