[PATCH] intelfb: Fix oops when changing video mode
Reported by: janis huang (Bugzilla Bug 5747)
Fix on oops in intelfb. Not sure what's happening, looks like
dinfo->name pointer is invalidated after initialization. Remove
intelfb_get_fix, it's not needed and move the majority of the code to
the initialization routine.
