Subject: [PATCH AUTOSEL 5.4 15/58] HID: hid-bigbenff: call hid_hw_stop() in case of error
Date: Thu, 5 Mar 2020 12:13:36 -0500 [thread overview]
Message-ID: <20200305171420.29595-15-sashal@kernel.org> (raw)
In-Reply-To: <20200305171420.29595-1-sashal@kernel.org>
From: Hanno Zulla <kontakt@hanno.de>
[ Upstream commit 976a54d0f4202cb412a3b1fc7f117e1d97db35f3 ]
It's required to call hid_hw_stop() once hid_hw_start() was called
previously, so error cases need to handle this. Also, hid_hw_close() is
not necessary during removal.
