Subject: [RFC 23/50] staging: vchi: Use vchiq's enum vchiq_reason
Date: Wed, 27 May 2020 13:53:28 +0200	[thread overview]
Message-ID: <20200527115400.31391-24-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200527115400.31391-1-nsaenzjulienne@suse.de>

enum vchi_callback_reason maps 1:1 to enum vchiq_reason, in an effort to
simplify things, let's use the later, and get rid of the extra
indirection.
