Building a kernel for imx_v4_v5_defconfig with CONFIG_USB_ULPI disabled, results in the following error: arch/arm/mach-imx/built-in.o: In function 'pca100_init': platform-mx2-emma.c:(.init.text+0x6788): undefined reference to 'otg_ulpi_create' platform-mx2-emma.c:(.init.text+0x682c): undefined reference to 'mxc_ulpi_access_ops' Fix this by providing a no-op definition of *otg_ulpi_create for the case when CONFIG_USB_ULPI is not defined.
