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.

Looks like I already have this one in my linux-next branch, but I think
Linus will handle any conflict that arises if this ends up coming from
both of us.

Thanks,

Yes, it should be a trivial merge.
