Hi all, After merging the usb-gadget tree, today's linux-next build (arm multi_v7_defconfig) failed like this: drivers/usb/dwc3/drd.c: In function 'dwc3_setup_role_switch': drivers/usb/dwc3/drd.c:551:23: error: assignment to 'usb_role_switch_set_t' {aka 'int (*)(struct usb_role_switch *, enum usb_role)'} from incompatible pointer type 'int (*)(struct device *, enum usb_role)' [-Werror=incompatible-pointer-types] 551 | dwc3_role_switch.set = dwc3_usb_role_switch_set; | ^ drivers/usb/dwc3/drd.c:552:23: error: assignment to 'usb_role_switch_get_t' {aka 'enum usb_role (*)(struct usb_role_switch *)'} from incompatible pointer type 'enum usb_role (*)(struct device *)' [-Werror=incompatible-pointer-types] 552 | dwc3_role_switch.get = dwc3_usb_role_switch_get; | ^ Caused by commit 8a0a13799744 ("usb: dwc3: Registering a role switch in the DRD code.") interacting with commit bce3052f0c16 ("usb: roles: Provide the switch drivers handle to the switch in the API") from the usb tree.
