linux-next: allyesconfig build failure in drivers/usb/gadget

[H Hartley Sweeten]

Hello all,

I'm not sure if this is a known issue or not...

I was trying an allyesconfig build of linux-next (next-20120224) and got this:

make[1]: *** [drivers/built-in.o] Error 1
make: *** [drivers] Error 2

It appears config.c, composite.c, usbstring.c, and epautoconf.c are not
actually built separately during the make but are #include'd by various
other sources. All of these files have functions that are not marked static
so we end up with the 'multiple definition' errors.

Should these files be compiled separately and treated as a gadget library?

Hartley
