Subject: [PATCH] drm/i915: Constify states passed to enable/disable/etc. encoder hooks
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: 5f88a9c61978b20acba4b5a76555eb3a4a03ab73
Patch-mainline: v4.15-rc1
References: FATE#322643 bsc#1055900
The enable/disable/etc. encoder hooks aren't supposed to alter the
state(s), so pass them as const. Unfortunately C lacks any kind of deep
const thingy, so this can't catch all abuses. But at least it acts as a
hint to the reader telling them not to mess about with the state(s).
V2: Update intel_tv_mode_find() and ironlake_edp_pll_on() as well
V3: Deal with intel_sdvo_connector_state
