I can't figure out how to reproduce this Sparse warning. I compiled drivers/staging/comedi/drivers/ni_mio_cs.c and it doesn't have it. I double checked by doing a `make drivers/staging/comedi/drivers/ni_mio_cs.i` that the ni_stc_dma_channel_select_bitfield is not ifdeffed out. Which version of Sparse are you using? Really the correct thing is to fix Sparse. regards, dan carpenter _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
