The original code has several issues: First, usb_phy_generic_register returns pointers of platform_device Second, the generic USB PHY driver is related to struct usb_phy, but not struct phy. So, in this code, it needs to use ci->usb_phy to get the pointer of struct usb_phy used at generic USB PHY driver. Would you mind sending the patches to fix them? -- Best Regards, Peter Chen -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
