Subject: [RFC 33/50] staging: vchi: Use struct vchiq_service_params
Date: Wed, 27 May 2020 13:53:38 +0200	[thread overview]
Message-ID: <20200527115400.31391-34-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200527115400.31391-1-nsaenzjulienne@suse.de>

For initialization, vchi has its own params structure, which is then
translated to vchiq's params structure. They are essentially the same,
so lets directly use vchiq's.
