From 3a8839bbb86da7968a792123ed2296d063871a52 Mon Sep 17 00:00:00 2001 From: Zijun Hu Date: Tue, 20 Aug 2024 19:01:27 +0800 Subject: [PATCH] usb: core: sysfs: Unmerge @usb3_hardware_lpm_attr_group in remove_power_attributes() 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().
