Subject: [PATCH 02/16] staging: vchiq_arm: rework close/remove_service IOCTLS
Date: Tue, 20 Nov 2018 15:53:37 +0100	[thread overview]
Message-ID: <20181120145351.30390-3-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20181120145351.30390-1-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.
