From: Chen-Yu Tsai Date: Wed, 21 Aug 2024 04:10:04 +0000 (+0800) Subject: ASoc: SOF: topology: Clear SOF link platform name upon unload X-Git-Tag: v6.11-rc7~18^2^2~4 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e0be875c5bf03a9676a6bfed9e0f1766922a7dbd;p=thirdparty%2Flinux.git ASoc: SOF: topology: Clear SOF link platform name upon unload The SOF topology loading function sets the device name for the platform component link. This should be unset when unloading the topology, otherwise a machine driver unbind/bind or reprobe would complain about an invalid component as having both its component name and of_node set: mt8186_mt6366 sound: ASoC: Both Component name/of_node are set for AFE_SOF_DL1 mt8186_mt6366 sound: error -EINVAL: Cannot register card mt8186_mt6366 sound: probe with driver mt8186_mt6366 failed with error -22 This happens with machine drivers that set the of_node separately. Clear the SOF link platform name in the topology unload callback.
