From 58f30d650c7f5275d4d57e62862970e1078af462 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 12 May 2017 11:35:17 +0200 Subject: ALSA: pcm: Build pcm notifier code conditionally The PCM notifier code is used only by OSS emulation layer, so we can build it conditionally for reducing the size.
