Subject: [PATCH 18/24] rt2x00: Merge allocation/free register components
Date: Sun, 16 Sep 2007 14:19:18 +0200 [thread overview]
Message-ID: <200709161419.19810.IvDoorn@gmail.com> (raw)
In-Reply-To: <200709161403.11332.IvDoorn@gmail.com>
The csr, eeprom and rf register components are always
allocated and freed at the same locations.
It will be easier if the 3 allocation and the 3 free functions
are merged into a single allocation and single free function
which can be used everywhere.
