Subject: ASoC: Intel: Skylake: Check for module list being NULL
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a35aeaee94dd5806907c400caf8293d7d7a60ebc;p=linux-beck.git

ASoC: Intel: Skylake: Check for module list being NULL

While clearing loaded module count, we should check first to see
if module list is NULL or not. Some distributions can ship with
no modules and thus list can be empty.
