Subject: [RFC 17/50] staging: vchi_common: Get rid of all unused definitions
Date: Wed, 27 May 2020 13:53:22 +0200	[thread overview]
Message-ID: <20200527115400.31391-18-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200527115400.31391-1-nsaenzjulienne@suse.de>

There is a series of structures and enums defined but never used. Get
rid of them.
