X-Git-Tag: v3.4-rc1~125^2~11^2~7^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e0e12a9282a879577ba8e35c73ff5d94ae1f50b9;p=platform%2Fkernel%2Flinux-stable.git

viafb: set correct polarity for second adapter

This patch sets the correct polarity for the second adapter when
viafb_SAMM_ON is set and viafb_dual_fb is not set. Just one step to
make this mode useful.
