[PATCH 17/33] block/ps3: remove driver_data direct access of struct device
Geert Uytterhoeven
Geert.Uytterhoeven at sonycom.com
Thu Jun 11 00:38:52 EST 2009
From: Roel Kluin <roel.kluin at 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.
[Geert: Use ps3_system_bus_[gs]et_driver_data() for ps3_system_bus_device]
