Subject: jsm: Remove the uart port on errors
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=abf4f6a51477a68fe144b0c62f10c410b0c41378;p=linux-beck.git

jsm: Remove the uart port on errors

If kzmalloc fails, the uart port is not removed causing a leak.
This patch just add another label that removes the uart when the
kzmalloc fails.
