-Wunused-but-set-parameter is finding stuff with current allmodconfig:
drivers/misc/mic/scif/scif_dma.c:118:27: warning: parameter 'ep' set but not
used [-Wunused-but-set-parameter]
drivers/net/ethernet/qlogic/qlcnic/qlcnic_83xx_hw.c:2156:8: warning: parameter
'function' set but not used [-Wunused-but-set-parameter]
drivers/net/ethernet/ti/tlan.c:1647:59: warning: parameter 'host_int' set but
not used [-Wunused-but-set-parameter]
drivers/usb/gadget/udc/pxa27x_udc.c:1828:74: warning: parameter 'driver' set
but not used [-Wunused-but-set-parameter]
and judging by changelogs, people were using it before,
but were too scared to change top level Makefile.
