From 2cd24c318cc943b54cbd2d855cee798314619c4e Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Fri, 11 Nov 2022 12:26:52 +0800 Subject: [PATCH] soundwire: intel_init: remove check on number of links MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The number of links is checked with a chip-dependent helper in the caller, remove the check in drivers/soundwire/intel_init.c This change makes intel_init.c hardware-agnostic - which is quite fitting for a layer that only creates auxiliary devices.
