From 4846a67eb5a1d7cac76e1b22f66e88a8cbbdff3f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 21 Mar 2016 12:56:46 +0100 Subject: [PATCH] ALSA: hda - Introduce pin_cvt_fixup() ops to hdmi parser For reducing the splat of is_haswell_plus() or such macros, this patch introduces pin_cvt_fixup() ops to hdmi_spec. For HSW+ and VLV+ codecs, set this ops so that the driver can call the Intel-specific workarounds appropriately. A gratis bonus that we can remove the mux_id argument from hdmi_choose_cvt(), too, since the fixup function always refers the mux_idx from the given per_pin object.
