Subject: [PATCH 22/50] staging: vchi: Use enum vchiq_bulk_mode instead of vchi's transmission flags
Date: Tue, 23 Jun 2020 18:42:08 +0200	[thread overview]
Message-ID: <20200623164235.29566-23-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20200623164235.29566-1-nsaenzjulienne@suse.de>

vchi has a set of transfer flags which almost map 1:1 to vchiq's own
transfer modes. For the sake of simplicity let's use the later and
delete vchi's.
