HID: core: allow concurrent registration of drivers
Detected on the Dell XPS 9365.
The laptop has 2 devices that benefit from the hid-generic auto-unbinding.
When those 2 devices are presented to the userspace, udev loads both wacom and
hid-multitouch. When this happens, the code in __hid_bus_reprobe_drivers() is
called concurrently and the second device gets reprobed twice.
An other bug in the power_supply subsystem prevent to remove the wacom driver
if it just finished its initialization, which basically kills the wacom node.
[jkosina@suse.cz: reformat changelog a bit]
Fixes c17a7476e4c4 ("HID: core: rewrite the hid-generic automatic unbind")
