From 2ba2dfa1fcc7ce5d2bf1716ec3d32b6fa0882e68 Mon Sep 17 00:00:00 2001 From: Jie Yang Date: Mon, 27 Apr 2015 21:20:59 +0800 Subject: [PATCH] ALSA: hda - Update to use the new jack kctls method Jack snd_kcontrols can now be created during snd_jack_new() or by later calling snd_jack_add_new_kctls(). This patch creates the jacks during the initialisation stage for both phantom and non phantom jacks.
