usb: gadget: pch_udc: Fix wrong return value
ISSUE: If the return value of pch_udc_pcd_init() is False, the return value of this function is unsettled. Since pch_udc_pcd_init() always returns 0, there is not actually the issue. CAUSE: If pch_udc_pcd_init() is True, the variable, retval, is not set for an appropriate value. Signed-off-by: Tomoya MORINAGA <tomoya.rohm@gmail.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
