    Subject[PATCH -next] tm6000: fix build errors
    From: Randy Dunlap <randy.dunlap@oracle.com>

    (1) tm6000 uses usb_*() interfaces, so it should depend on USB.

    drivers/built-in.o: In function `tm6000_usb_disconnect':
    tm6000-cards.c:(.text+0x4abb44): undefined reference to `usb_put_dev'
    drivers/built-in.o: In function `tm6000_usb_probe':
    tm6000-cards.c:(.text+0x4ac923): undefined reference to `usb_get_dev'
    tm6000-cards.c:(.text+0x4ac93c): undefined reference to `usb_set_interface'
    drivers/built-in.o: In function `tm6000_read_write_usb':
    (.text+0x4ad274): undefined reference to `usb_control_msg'
    drivers/built-in.o: In function `tm6000_uninit_isoc':
    tm6000-video.c:(.text+0x4b00d5): undefined reference to `usb_kill_urb'
    tm6000-video.c:(.text+0x4b00e4): undefined reference to `usb_unlink_urb'
    tm6000-video.c:(.text+0x4b013c): undefined reference to `usb_buffer_free'
    tm6000-video.c:(.text+0x4b014b): undefined reference to `usb_free_urb'
    drivers/built-in.o: In function `tm6000_prepare_isoc':
    tm6000-video.c:(.text+0x4b0773): undefined reference to `usb_alloc_urb'
    tm6000-video.c:(.text+0x4b0835): undefined reference to `usb_buffer_alloc'
    drivers/built-in.o: In function `tm6000_irq_callback':
    tm6000-video.c:(.text+0x4b1ad3): undefined reference to `usb_submit_urb'
    drivers/built-in.o: In function `tm6000_module_init':
    tm6000-cards.c:(.init.text+0x24499): undefined reference to `usb_register_driver'
    drivers/built-in.o: In function `tm6000_module_exit':
    tm6000-cards.c:(.exit.text+0x5cb0): undefined reference to `usb_deregister'

    (2) tm6000-alsa uses interfaces from tm6000-core, so when they are
    both built as modules, the core interfaces need to be exported.

    ERROR: "tm6000_set_reg" [drivers/staging/tm6000/tm6000-alsa.ko] undefined!
    ERROR: "tm6000_get_reg" [drivers/staging/tm6000/tm6000-alsa.ko] undefined!
