From bb814c396af777c31ed168ce57f620967dd133f1 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 2 Jan 2015 12:24:49 +0100 Subject: [PATCH] ALSA: emu10k1: Remove always NULL parameters The various PCM and hwdep allocation functions in this driver take a pointer to a pointer of a PCM/hwdep where if this parameter is provided the newly allocated object is stored. All callers pass NULL though, so remove the parameter.
