FYI, I see the build breakage when using ARM multi_v7_defconfig,
with the mass-storage gadget enabled and dwc2 enabled for
peripheral-only mode:

  CC      init/version.o
  LD      init/built-in.o
drivers/built-in.o: In function `dwc2_hc_set_even_odd_frame':
:(.text+0x21ca0c): undefined reference to `dwc2_hcd_get_frame_number'
drivers/built-in.o: In function `dwc2_handle_common_intr':
:(.text+0x21f5dc): undefined reference to `dwc2_hcd_start'
:(.text+0x21f660): undefined reference to `dwc2_hcd_start'
