Subject: [PATCH v2 6/7] ASoC: Intel: avs: Expose common PCM functions
Date: Tue, 3 Nov 2026 14:49:57 +0100 [thread overview]
Message-ID: <20261103134958.2089136-7-cezary.rojewski@intel.com> (raw)
In-Reply-To: <20261103134958.2089136-1-cezary.rojewski@intel.com>
All the PCM operations are currently bundled together within the pcm.c
file regardless of which transfer type they cover. To allow for
splitting them, provide a header that exposes the common operations
outside.
