Subject: [PULL 08/30] audio: split pcm_ops function get_buffer_in
Date: Fri, 15 Jan 2021 14:21:24 +0100 [thread overview]
Message-ID: <20210115132146.1443592-9-kraxel@redhat.com> (raw)
In-Reply-To: <20210115132146.1443592-1-kraxel@redhat.com>
From: Volker Rümelin <vr_qemu@t-online.de>
Split off pcm_ops function run_buffer_in from get_buffer_in and
call run_buffer_in before get_buffer_in.
The next patch only needs the generic buffer management part
from audio_generic_get_buffer_in().
