Subject: [PATCH v5 3/3] PCI: endpoint: pci_epf_create: remove goto labels
Date: Wed, 28 Feb 2018 18:32:20 +0100 [thread overview]
Message-ID: <20180228173220.544-4-embedded24@evers-fischer.de> (raw)
In-Reply-To: <20180228173220.544-1-embedded24@evers-fischer.de>
From: Rolf Evers-Fischer <rolf.evers.fischer@aptiv.com>
Removes the goto labels completely, handles the errors at the
respective call site and just returns instead of jumping around.
Signed-off-by: Rolf Evers-Fischer <rolf.evers.fischer@aptiv.com>
