From 25befdf32aa407ac21d8b2aa1257ff666fb783b2 Mon Sep 17 00:00:00 2001 From: Bard Liao Date: Wed, 18 Dec 2024 16:01:55 +0800 Subject: [PATCH] soundwire: generic_bandwidth_allocation: count the bandwidth of active streams only MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit sdw_compute_group_params() should only count payload bandwidth of the active streams which is in the ENABLED and DISABLED state in the bus. And add the payload bandwidth of the stream that calls sdw_compute_group_params() in sdw_prepare_stream().
