Commit cc92f6818f6e ("usb: musb: Populate new IO functions for blackfin") defines bfin_fifo_offset function without using it: drivers/usb/musb/blackfin.c:36:12: warning: ‘bfin_fifo_offset’ defined but not used [-Wunused-function] static u32 bfin_fifo_offset(u8 epnum) ^~~~~~~~~~~~~~~~ Adding bfin_fifo_offset to bfin_ops fixes this warning and allows musb core to call this function instead of default_fifo_offset.
