[PATCH 1/6] i2c: cpm: use devm_ functions

[Julia Lawall]

From: Julia Lawall <Julia.Lawall at lip6.fr>

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
