| |
2.6.34-stable review patch. If anyone has any objections, please let me know.
------------------ From: Karsten Wiese <fzuuzf@googlemail.com>
commit 6e0032f0ae4440e75256bee11b163552cae21962 upstream.
PORT_HOTPLUG_EN has allready been setup in i915_driver_irq_postinstall(), when intel_dp_detect() runs.
Delete the DP[BCD]_HOTPLUG_INT_EN defines, they are not referenced anymore.
I found this while searching for a fix for https://bugzilla.redhat.com/show_bug.cgi?id=528312
