From: Florian Tobias Schandinat Date: Tue, 10 Aug 2010 00:45:06 +0000 (+0000) Subject: viafb: reduce viafb_set_iga_path usage X-Git-Tag: v2.6.37-rc1~80^2~21 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=661c65cd0ce180d5e3a3e05f08fc9e64cedcf91c;p=profile%2Fivi%2Fkernel-x86-ivi.git 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.
