Subject: [PATCH AUTOSEL 6.0 23/44] platform/x86: asus-wmi: add missing pci_dev_put() in asus_wmi_set_xusb2pr()
Date: Wed, 23 Nov 2022 07:40:32 -0500 [thread overview]
Message-ID: <20221123124057.264822-23-sashal@kernel.org> (raw)
In-Reply-To: <20221123124057.264822-1-sashal@kernel.org>
From: Xiongfeng Wang <wangxiongfeng2@huawei.com>
[ Upstream commit d0cdd85046b15089df71a50548617ac1025300d0 ]
pci_get_device() will increase the reference count for the returned
pci_dev. We need to use pci_dev_put() to decrease the reference count
before asus_wmi_set_xusb2pr() returns.
