Subject: drm/i915: kill intel_ddc_probe
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4d678e1670ad3c7240d559c98e481b43342a2974;p=openwrt%2Fstaging%2Fblogic.git

drm/i915: kill intel_ddc_probe

We have way too much lying hardware to rely on a simple "does someone
answer on the ddc i2c address?" check. And now it's unused, so just
kill it.
