From 50b8d94e1819768e8eccae4d24698a17b8940776 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 2 Jan 2015 12:24:48 +0100 Subject: [PATCH] ALSA: ens1370: Remove always NULL parameters The various PCM and MIDI allocation functions in this driver take a pointer to a pointer of a PCM/MIDI object where if this parameter is provided the newly allocated object is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit shorter and cleaner.
