From 5e56bcea5017b7b7808df60f21ef01738b6e1a25 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 26 Feb 2015 12:29:03 +0100 Subject: ALSA: hda - Allow driver to add vendor-specific verbs for regmap Codecs may have own vendor-specific verbs, and we need to allow each driver to give such verbs for cached accesses. Here a verb can be put into a single array and looked through it at readable and writeable callbacks.
