[PATCH 3.16 005/306] drm/i915/vlv: Make intel_crt_reset() per-encoder

Show all headers | View raw

3.16.40-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Lyude <cpaul@redhat.com>

commit 28cf71ce3e206db1c3f30b3da31e7b48b2269e4c upstream.

This lets call intel_crt_reset() in contexts where IRQs are disabled and
as such, can't hold the locks required to work with the connectors.
