Subject[[PATCH 08/11]] viafb: reduce viafb_set_iga_path usage
DateThu, 12 Aug 2010 00:08:42 +0000
viafb: reduce viafb_set_iga_path usage

The result of viafb_set_iga_path can change after init only in the
hotplug ioctl. So we can move it there rather than doing it always
when a new mode is set. The setup during init is done via a call
from the init chip funtion.
This change enables a stable mapping between the old device scheme
and a new more powerfull one.
