Subject: [PATCH] ps3: remove driver_data direct access of struct device
To avoid direct access to the driver_data pointer in struct device, the
functions dev_get_drvdata() and dev_set_drvdata() should be used.
Signed-off-by: Roel Kluin <roel.kluin@...il.com>

Please review. especially note that I removed a
kfree(dev->sbd.core.driver_data);
Is that correct?
