Subject: [PATCH v2] HID: hiddev: change hiddev_connect() to return bool
Since hid_connect() only cares about hiddev_connect() succeeding or
failing, there is no need for this function to return an int and it can
return a bool instead.

Hi,
No idea why my local build did not complain about the obvious mistake
on the previous version of the patch.
Sorry about that,
Luis
