From 93724affb195149df6f7630901d878f6e273fa02 Mon Sep 17 00:00:00 2001
From: Hauke Mehrtens <hauke@hauke-m.de>
Date: Thu, 11 Jun 2015 22:57:37 +0200
Subject: [PATCH] USB: bcma: use devm_kzalloc
Instead of manually handling the frees use devm. There was also a free
missing in the unregister call which is not needed with devm.
