Subject: [PATCH 02/16] staging: vchiq_arm: rework close/remove_service IOCTLS
Date: Wed, 14 Nov 2018 13:59:28 +0100 [thread overview]
Message-ID: <20181114125942.25163-3-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20181114125942.25163-1-nsaenzjulienne@suse.de>
The implementation of both IOCTLS was the same except for one function
call. This joins both implementations and updates the code to avoid
unneeded indentations.
