Subject: [PATCH 04/18] ALSA: core: timer: remove redundant assignment
Date: Wed, 2 Sep 2020 16:21:19 -0500 [thread overview]
Message-ID: <20200902212133.30964-5-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20200902212133.30964-1-pierre-louis.bossart@linux.intel.com>
Cppcheck complains about a possible NULL pointer dereference but it
actually looks like the NULL assignment is not needed (same loop is
used in other parts of the file without it).
