From e99b8f05f7a5bee478da68d2f9fa8fabb617cf2c Mon Sep 17 00:00:00 2001 From: Bard Liao Date: Thu, 21 Nov 2024 17:20:25 +0800 Subject: [PATCH] soundwire: generic_bandwidth_allocation: count the bandwidth of active streams only 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().
