Subject: [PATCH v8 1/4] i2c-mpc: use __devinit[data] for initialization functions and data
Date: Wed, 17 Feb 2010 11:19:17 +0100 [thread overview]
Message-ID: <1266401960-19127-2-git-send-email-wg@grandegger.com> (raw)
In-Reply-To: <1266401960-19127-1-git-send-email-wg-5Yr1BZd7O62+XT7JhA+gdA@public.gmane.org>
From: Wolfgang Grandegger <wg-ynQEQJNshbs@public.gmane.org>
"__devinit[data]" has not yet been used for all initialization functions
and data. To avoid truncating lines, the struct "mpc_i2c_match_data" has
been renamed to "mpc_i2c_data", which is even the better name.
