Match the iio_buffer_register stub signature up to the real function and make the second parameter const. This fixes a the following warnings if CONFIG_IIO_BUFFER is disabled: drivers/staging/iio/accel/adis16201_core.c: In function ‘adis16201_probe’: drivers/staging/iio/accel/adis16201_core.c:536: warning: passing argument 2 of ‘iio_buffer_register’ discards qualifiers from pointer target type drivers/staging/iio/accel/adis16203_core.c: In function ‘adis16203_probe’: drivers/staging/iio/accel/adis16203_core.c:468: warning: passing argument 2 of ‘iio_buffer_register’ discards qualifiers from pointer target type drivers/staging/iio/accel/adis16204_core.c: In function ‘adis16204_probe’: drivers/staging/iio/accel/adis16204_core.c:527: warning: passing argument 2 of ‘iio_buffer_register’ discards qualifiers from pointer target type drivers/staging/iio/accel/adis16209_core.c: In function ‘adis16209_probe’: drivers/staging/iio/accel/adis16209_core.c:542: warning: passing argument 2 of ‘iio_buffer_register’ discards qualifiers from pointer target type drivers/staging/iio/accel/adis16240_core.c: In function ‘adis16240_probe’: drivers/staging/iio/accel/adis16240_core.c:588: warning: passing argument 2 of ‘iio_buffer_register’ discards qualifiers from pointer target type Signed-off-by: Lars-Peter Clausen <lars@xxxxxxxxxx> --- include/linux/iio/buffer.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/iio/buffer.h b/include/linux/iio/buffer.h index 0270405..f3eea18 100644 --- a/include/linux/iio/buffer.h +++ b/include/linux/iio/buffer.h @@ -195,7 +195,7 @@ bool iio_validate_scan_mask_onehot(struct iio_dev *indio_dev, #else /* CONFIG_IIO_BUFFER */ static inline int iio_buffer_register(struct iio_dev *indio_dev, - struct iio_chan_spec *channels, + const struct iio_chan_spec *channels, int num_channels) { return 0; -- 1.8.0 -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
