Subject: [PATCH 1/3] ALSA: hal2: Use common error handling code in hal2_probe()
Date: Sat, 11 Nov 2017 19:11:55 +0100	[thread overview]
Message-ID: <efebe781-a78c-5bec-f519-752d46661687@users.sourceforge.net> (raw)
In-Reply-To: <118a96d5-c52a-fd22-23d5-28f20de7ff22@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>

Add a jump target so that a bit of exception handling can be better reused
at the end of this function.

This issue was detected by using the Coccinelle software.
