Subject: [RFC 37/50] staging: vchiq: Unify fourcc definition mechanisms
Date: Wed, 27 May 2020 13:53:42 +0200 [thread overview]
Message-ID: <20200527115400.31391-38-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200527115400.31391-1-nsaenzjulienne@suse.de>
There is already enough duplication with regard to fourcc generation in
the kernel. Let's at least use the same macro all over the vchiq
ecosystem.
