From 1b16416fda21a8c5704bce809e0d7387bbfb097d Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 2 Jan 2015 12:24:54 +0100 Subject: ALSA: trident: 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.
