Hmm but the .config has the following: CONFIG_TYPEC_UCSI=y CONFIG_USB_ROLE_SWITCH=m So I'm guessing this patch also requires a Kconfig change to disallow the above combination? If so, should UCSI have a "depends" or a "select" on USB_ROLE_SWITCH? Jack -- The Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project
