[PATCH v7 1/4] i2c-mpc: use __devinit[data] for initialization functions and data
Wolfgang Grandegger

Thu Feb 11 01:55:08 EST 2010
From: Wolfgang Grandegger <wg at denx.de>
"__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.
