The ad7298 drivers buffer implementation uses the IIO kfifo buffer, so it needs to select IIO_KFIFO_BUF. Otherwise (if no other driver selects the symbol) the following linker error will occur: drivers/built-in.o: In function `ad7298_register_ring_funcs_and_init': (.text+0x245cf2): undefined reference to `iio_kfifo_allocate' drivers/built-in.o: In function `ad7298_register_ring_funcs_and_init': (.text+0x245d7d): undefined reference to `iio_kfifo_free' drivers/built-in.o: In function `ad7298_ring_cleanup': (.text+0x245dcd): undefined reference to `iio_kfifo_free' Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Reported-by: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
