X-Git-Tag: v3.4.12~69
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=33822abf1d7190dd8dab1da87661bde5208de6c8;p=platform%2Fkernel%2Flinux-stable.git

drm/i915: extract connector update from intel_ddc_get_modes() for reuse

commit 4eab81366465aedcfd26de960c595bc03599c09f upstream.

Refactor the connector update part of intel_ddc_get_modes() into a separate
intel_connector_update_modes() function for reuse. No functional changes.
