Arnd Bergmann 0bf048abeb staging: emxx_udc: allow modular build ... A change to the usb gadget core allowed certain API functions to be part of a loadable module, which breaks having emxx_udc built-in: drivers/staging/built-in.o: In function `nbu2ss_drv_probe': (.text+0x2428): undefined reference to `usb_ep_set_maxpacket_limit' The original patch already fixed tons of other cases that have the added dependency but apparently missed this one that now appears in an ARM allmodconfig build. This patch makes the symbol "tristate", which lets the Kconfig dependency tracking handle it correctly. To make the module actually usable, I also revert 0af61e66ee ("drivers/staging: make emxx_udc.c explicitly non-modular"), which Paul Gortmaker added after noticing that the Kconfig symbol was 'bool'. Compared to the original version however, I leave out the '__exit' annotation on the remove callback, as Paul pointed out that this was incorrect.
