Subject: [PATCH 09/11] Fix hw mode registration with mac80211.
Date: Sun, 17 Feb 2008 17:35:55 +0100	[thread overview]
Message-ID: <200802171735.56101.IvDoorn@gmail.com> (raw)
In-Reply-To: <200802171730.44353.IvDoorn@gmail.com>

From: Gertjan van Wingerde <gwingerde@kpnplanet.nl>

The supported_bands field of struct hw_mode_spec now represents a bitfield,
so bitfield operators need to be tested with when setting the band data.

The current code generates the following warning:
