Subject[PATCH 59/64] block/ps3: remove driver_data direct access of struct device
Date
From: Roel Kluin <roel.kluin@gmail.com>

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.
