Subject: [PATCH 09/22] staging: vc04_services: Get rid of vchiq_platform_videocore_wanted()
Date: Fri, 24 Jan 2020 15:46:03 +0100	[thread overview]
Message-ID: <20200124144617.2213-10-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200124144617.2213-1-nsaenzjulienne@suse.de>

The function always returns true, which makes a whole bunch of code
useless.
