commit 52fb7bcea0c6edc713405ff73a82802006f132e5
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7MU59

--------------------------------

[ Upstream commit d0cdd850 ]

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.
