musb: fix prefetch build failure
Mike Frysinger [Wed, 25 May 2011 12:13:24 +0000 (08:13 -0400)]
After the prefetch/list.h restructure, drivers need to explicitly include
linux/prefetch.h in order to use the prefetch() function.  Otherwise, the
current driver fails to build:

drivers/usb/musb/musb_core.c: In function 'musb_write_fifo':
drivers/usb/musb/musb_core.c:219: error: implicit declaration of function 'prefetch'
make[3]: *** [drivers/usb/musb/musb_core.o] Error 1
