Subject: [PATCH] vesafb: use platform_driver_probe() instead of
platform_driver_register()
To: u.kleine-koenig@xxxxxxxxxxxxxx, gregkh@xxxxxxx
Cc: linux-kernel@xxxxxxxxxxxxxxx
Commit c2e13037e6794bd0d9de3f9ecabf5615f15c160b introduced a huge
amount of section mismatch warnings in vesafb code. Rather than
converting all of the annotations, do the obvious and revert the
__init -> __devinit change, and use the recommended (in that patch)
alternative to calling platform_driver_register(): vesafb depends on
information obtained from by kernel at boot time, cannot be a module,
and no post-boot devices can ever show up.
