hid: thingm: reorder calls in thingm_probe
When reviewing another thingm patch Benjamin Tissoires pointed out the following: "The problem here is that hid_hw_start() is called before thingm_version() which allows user space to briefly introduce races between thingm_version() and any hidraw requests. The mutex will not help here as it is initialized after hid_hw_start() and only used for protecting the concurrent access of the rgb." Avoid this possible issue by calling hid_hw_start() later in the probe function. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
