#1653549 — [PATCH] HID: asus: Stop underlying hardware on remove

Subject[PATCH] HID: asus: Stop underlying hardware on remove
Message-ID<tMWfw-3DM-11@gated-at.bofh.it>
From: Carlo Caione <carlo@endlessm.com>

We are missing a call to hid_hw_stop() on the remove hook.
Among other things this is causing an Oops when (re-)starting GNOME /
upowerd / ... after the module has been already rmmod-ed.
