6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx> commit 3a8839bbb86da7968a792123ed2296d063871a52 upstream. Device attribute group @usb3_hardware_lpm_attr_group is merged by add_power_attributes(), but it is not unmerged explicitly, fixed by unmerging it in remove_power_attributes().
