[PATCH v3 1/3] i2c-mpc: use __init[data] for initialization functions and data

Wolfgang Grandegger wg at grandegger.com
Wed Jan 27 06:28:13 EST 2010


From: Wolfgang Grandegger <wg at denx.de>

"__devinit[data]" has been renamed to "__init[data]" as this is not
a hotplugable device. Futhermore, all initialization functions and
data are now marked properly. To avoid truncating lines, the struct
"mpc_i2c_match_data" has been renamed to "mpc_i2c_data", which is
even the better name.
