Subject: [PATCH v3 04/15] audio: inline function audio_pcm_sw_get_rpos_in()
Date: Tue, 1 Mar 2022 20:13:00 +0100 [thread overview]
Message-ID: <20220301191311.26695-4-vr_qemu@t-online.de> (raw)
In-Reply-To: <3d0bd2ac-e5b9-9cf6-c98f-c047390a3ec5@t-online.de>
Simplify code by inlining function audio_pcm_sw_get_rpos_in()
at the only call site and remove the duplicated audio_bug()
test.
