Revision 0eb808eb753cd44e740da8e64f5c97a2a8e07578 authored by Geert Uytterhoeven on 10 March 2014, 22:49:52 UTC, committed by Linus Torvalds on 11 March 2014, 00:26:21 UTC
This avoids bad interactions with code using identifiers called "ffs":

  drivers/usb/gadget/f_fs.c: In function 'ffsmod_init':
  drivers/usb/gadget/f_fs.c:2693:494: error: 'ffsusb_func' undeclared (first use in this function)
  drivers/usb/gadget/f_fs.c:2693:494: note: each undeclared identifier is reported only once for each function it appears in
  drivers/usb/gadget/f_fs.c: In function 'ffsmod_exit':
  drivers/usb/gadget/f_fs.c:2693:677: error: 'ffsusb_func' undeclared (first use in this function)
  drivers/usb/gadget/f_fs.c: At top level:
  drivers/usb/gadget/f_fs.c:2693:35: warning: 'kernel_ffsusb_func' defined but not used [-Wunused-variable]
  drivers/usb/gadget/f_fs.c: In function 'ffsmod_init':
  drivers/usb/gadget/f_fs.c:2693:15: warning: control reaches end of non-void function [-Wreturn-type]
