From: Jani Nikula Date: Tue, 28 Mar 2017 14:59:01 +0000 (+0300) Subject: drm/i915/dp: use known correct array size in rate_to_index X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3194102439f6acb0b43f36cc909c04adf3ad97e3;p=openwrt%2Fstaging%2Fblogic.git drm/i915/dp: use known correct array size in rate_to_index I can't think of a real world bug this could cause now, but this will be required in follow-up work. While at it, change the parameter order to be slightly more sensible.
