The newly added OTG support has an obvious uninitialized variable access that gcc warns about: drivers/phy/phy-rockchip-inno-usb2.c: In function 'rockchip_chg_detect_work': drivers/phy/phy-rockchip-inno-usb2.c:717:7: error: 'tmout' may be used uninitialized in this function [-Werror=maybe-uninitialized] This replaces the use of the uninitialized variable with what the value was in the previous USB_CHG_STATE_WAIT_FOR_DCD state.
