4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Xu Yang <xu.yang_2@xxxxxxx>
commit ff2b89de471da942a4d853443688113a44fd35ed upstream.
When CONFIG_USB_OTG is not set, mxs_phy_is_otg_host() will always return
false. This behaviour is wrong. Since phy.last_event will always be set
for either host or device mode. Therefore, CONFIG_USB_OTG condition
can be removed.
Fixes: 5eda42aebb76 ("usb: phy: mxs: fix getting wrong state with mxs_phy_is_otg_host()")
