[PATCH] intelfb/fbdev: Save info->flags in a local variable
Reported by: Pavel Kysilka (Bugzilla Bug 5059)
The intelfb driver does not keep resolution set with fbset after
switching to anot console and back.
Steps to reproduce:
initial options: tty1,tty2 - 1024x768-60
1) tty1 - fbset after booting (1024x768-60)
2) tty1 - fbset 800x600-100
tty1: 800x600-100
3) swith to tty2, swith to tty1
tty1: 1024x768-60 (the same resolution as default from kernel booting)
This bug is caused by intelfb unintentionally destroying info->flags in
set_par(). Therefore the flag, FBINFO_MISC_USEREVENT used to notify
fbcon of a mode change was cleared causing the above problem. This bug
though is not intelfb specific, as other drivers may also be affected.
The fix is to save info->flags in a local variable before calling any
of the driver hooks. A more definitive fix (for post 2.6.13) is to
separate info->flags into one that is set by the driver and another that
is set by core fbdev/fbcon.
