vesafb: use platform_driver_probe() instead of platform_driver_register()
Commit c2e13037e6794bd0d9de3f9ecabf5615f15c160b ("platform-drivers: move probe to .devinit.text in drivers/video") 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.
