[PATCH 58/64] s390: remove driver_data direct access of struct device

From: Greg Kroah-Hartman
Date: Tue Jun 16 2009 - 02:06:52 EST

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.

Thanks to Sebastian Ott <sebott@xxxxxxxxxxxxxxxxxx> for fixing a few
typos in my original version of this patch.
