From 05852448690d7d810175f8ceccefba083525aa89 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 3 Mar 2015 15:40:08 +0100 Subject: ALSA: hda - Support indirect execution of verbs Add an overriding exec_verb op to struct hdac_device so that the call via snd_hdac_exec_verb() can switch to a different route depending on the setup. The codec driver sets this field so that it can handle the errors or applying quirks appropriately. Furthermore, this mechanism will be used for smooth transition for the regmap support in later patches.
