This breaks the build:
drivers/usb/gadget/udc/gr_udc.c: In function ‘gr_dfs_create’:
drivers/usb/gadget/udc/gr_udc.c:211:57: error: ‘usb_debug_root’ undeclared (first use in this function)
211 | dev->dfs_root = debugfs_create_dir(dev_name(dev->dev), usb_debug_root);
| ^~~~~~~~~~~~~~
drivers/usb/gadget/udc/gr_udc.c:211:57: note: each undeclared identifier is reported only once for each function it appears in
make[4]: *** [scripts/Makefile.build:265: drivers/usb/gadget/udc/gr_udc.o] Error 1

so I've dropped it from the patch series.

Please fix up and resend.

And of course, always test-build your patches before you send them
out...
