From 8f1ec181b12e8ac04e9690f1b122a6779ad2acc2 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Mon, 10 Oct 2016 18:04:02 +0300 Subject: [PATCH] drm/i915/audio: use the same code for updating audio config It gets fragile to duplicate the code for updating HSW_AUD_CFG. The only change should be that the hdmi pixel clock is also updated in i915_audio_component_sync_audio_rate(), but it should not be any different.
