From 38c4718121804317e00a3a905612d17485f754c0 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 2 Jan 2015 12:24:55 +0100 Subject: ALSA: ymfpci: Remove always NULL parameters The various PCM allocation functions in this driver take a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit shorter and cleaner.
