Replacing zero-length arrays with C99 flexible-array members since they are obsolete. Use the new DECLARE_FLEX_ARRAY() auxiliary macro instead of defining a zero-length array. This fixes warnings such as: ./drivers/iio/accel/adxl367_spi.c:38:6-17: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays) Signed-off-by: Atul Raut <rauji.raut@xxxxxxxxx> --- drivers/iio/accel/adxl367_spi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/iio/accel/adxl367_spi.c b/drivers/iio/accel/adxl367_spi.c index 118c894015a5..9dc61cb45fc5 100644 --- a/drivers/iio/accel/adxl367_spi.c +++ b/drivers/iio/accel/adxl367_spi.c @@ -35,7 +35,7 @@ struct adxl367_spi_state { */ u8 reg_write_tx_buf[1] __aligned(IIO_DMA_MINALIGN); u8 reg_read_tx_buf[2]; - u8 fifo_tx_buf[1]; + DECLARE_FLEX_ARRAY(u8, fifo_tx_buf); }; static int adxl367_read_fifo(void *context, __be16 *fifo_buf, -- 2.34.1
