From: Randy Dunlap <[email protected]> Fix build errors in phy-rockchip-inno-usb2.c. The driver uses extcon interfaces so it should depend on EXTCON.
Fixes these build errors: drivers/built-in.o: In function `rockchip_usb2phy_otg_sm_work': phy-rockchip-inno-usb2.c:(.text+0x2bcb): undefined reference to `extcon_get_state' phy-rockchip-inno-usb2.c:(.text+0x2cd4): undefined reference to `extcon_set_state_sync' phy-rockchip-inno-usb2.c:(.text+0x2cec): undefined reference to `extcon_set_state_sync' phy-rockchip-inno-usb2.c:(.text+0x2d2d): undefined reference to `extcon_get_state' drivers/built-in.o: In function `rockchip_usb2phy_probe': phy-rockchip-inno-usb2.c:(.text+0x31d7): undefined reference to `extcon_get_edev_by_phandle' phy-rockchip-inno-usb2.c:(.text+0x321a): undefined reference to `devm_extcon_dev_allocate' phy-rockchip-inno-usb2.c:(.text+0x3230): undefined reference to `devm_extcon_dev_register' phy-rockchip-inno-usb2.c:(.text+0x375a): undefined reference to `extcon_register_notifier' Found in linux-next but is also needed in mainline.
