From 1cf05ba2cafa079a943c2cbae51b2f2c2e247466 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 5 Feb 2017 08:58:46 +0100 Subject: [PATCH] ALSA: pcm: Define dummy snd_pcm_suspend() for CONFIG_PM=n ... so that the driver can avoid ifdef's for the dead PM callbacks. The compiler should optimize them out in anyway.
