ACPI / battery: Safe unregistering of hooks A hooking API was implemented for 4.17 in fa93854f7a7ed63d followed by hooks for Thinkpad laptops in 2801b9683f740012. The Thinkpad drivers did not support the Thinkpad 13 and the hooking API crashes on unsupported batteries by altering a list of hooks during unsafe iteration. Thus, Thinkpad 13 laptops could no longer boot. Additionally, a lock was kept in place and debugging information was printed out of order.
