Subject: [PATCH 08/23] audio: split pcm_ops function get_buffer_in
Date: Sun, 10 Jan 2021 11:02:24 +0100
Message-ID: <20210110100239.27588-8-vr_qemu@t-online.de> (raw)
In-Reply-To: <9315afe5-5958-c0b4-ea1e-14769511a9d5@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().
