[ Upstream commit e0be875c5bf03a9676a6bfed9e0f1766922a7dbd ]
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.
