6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arend van Spriel <arend.vanspriel@xxxxxxxxxxxx>
[ Upstream commit b822015a1f57268f5b2ff656736dc4004e7097da ]
When the brcmf_fwvid_attach() fails the driver instance is not added
to the vendor list. Hence we should not try to delete it from that
list when the brcmf_fwvid_detach() function is called in cleanup path.
Cc: stable@xxxxxxxxxxxxxxx # 6.2.x
Fixes: d6a5c562214f ("wifi: brcmfmac: add support for vendor-specific firmware api")
