Subject: [cocci] [PATCH] ASoC: SOF: ipc4-topology: Improve unlocking of a mutex in sof_ipc4_widget_free()
Date: Sat, 10 Jun 2023 13:36:37 +0200	[thread overview]
Message-ID: <3a7476b6-2ae9-494e-1840-0915ddf47c2f@web.de> (raw)
In-Reply-To: <20230322181830.574635-1-jyri.sarha@linux.intel.com>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 10 Jun 2023 12:40:09 +0200

Add a jump target so that a call of the function “mutex_unlock”
is stored only once in this function implementation.
