Subject: drm/i915: Fix primary plane offset on HSW
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=bc1c91ebe31dfbc3a013adccbec6131d63efc8cf;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: Fix primary plane offset on HSW

Haswell consolidates DSP_TILEOFF and DSP_LINOFF into DSP_OFFSET (aka
PRI_OFFSET).
