From 023dfedec1478d506ba42d45f7993578fe38fa11 Mon Sep 17 00:00:00 2001 From: Bard Liao Date: Tue, 3 Feb 2026 19:15:45 +0800 Subject: [PATCH] ASoC: SOF: Intel: allow module parameter override BT link to 0 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The existing code test if (bt_link_mask_override) to overwrite the BT link mask. This doesn't allow user to disable the BT link mask. User may want to disable the BT link when it is detected by the NHLT.
