6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Armin Wolf <W_Armin@xxxxxx> [ Upstream commit 307004e8b254ad28e150b63f299ab9caa4bc7c3e ] It seems that when the driver is built-in, the HID bus is initialized after the driver is loaded, which whould cause module_hid_driver() to fail. Fix this by registering the driver after the HID bus using late_initcall() in accordance with other hwmon HID drivers.
