   4 Subject: [PATCH 06/29] usb: fotg210: Fix Kconfig for USB host modules
   5
   6 The kernel robot reports a link failure when activating the
   7 FOTG210 host subdriver with =y on a system where the USB host
   8 core is a module (CONFIG_USB=m).
   9
  10 This is a bit of special case, so mimic the Kconfig incantations
  11 from DWC3: let the subdrivers for host or peripheral depend
  12 on the host or gadget support being =y or the same as the
  13 FOTG210 core itself.
  14
  15 This should ensure that either:
  16
  17 - The host (CONFIG_USB) or gadget (CONFIG_GADGET) is compiled
  18   in and then the FOTG210 can be either module or compiled
  19   in.
  20
  21 - The host or gadget is modular, and then the FOTG210 module
  22   must be a module too, or we cannot resolve the symbols
  23   at link time.
