From: Sebastian Andrzej Siewior Date: Thu, 24 Nov 2016 16:10:13 +0000 (+0100) Subject: net/iucv: Use explicit clean up labels in iucv_init() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9c6bafab03dec222237b6eb8b5adf5c18ec76264;p=linux-beck.git net/iucv: Use explicit clean up labels in iucv_init() Ursula suggested to use explicit labels for clean up in the error path instead of one `out_free' label, which handles multiple exits, introduced in commit 38b482929e8f ("net/iucv: Convert to hotplug state machine").
