Subject: [PATCH v2] mrf24j40: Fix en error handling path in 'mrf24j40_probe()'
Date: Sat,  8 Jul 2017 10:40:13 +0200	[thread overview]
Message-ID: <20170708084013.18620-1-christophe.jaillet@wanadoo.fr> (raw)

If this check fails, we must release some resources as done everywhere
else in this function before returning an error code.
