Because zero-length arrays are obsolete, replacing them with C99 flexible-array members. Instead of defining a zero-length array, use the new DECLARE_FLEX_ARRAY() auxiliary macro. This fixes warnings such as: ./drivers/net/wireless/ath/ath6kl/usb.c:109:8-12: 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/net/wireless/ath/ath6kl/usb.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/wireless/ath/ath6kl/usb.c b/drivers/net/wireless/ath/ath6kl/usb.c index 5220809841a6..bb3771a3897c 100644 --- a/drivers/net/wireless/ath/ath6kl/usb.c +++ b/drivers/net/wireless/ath/ath6kl/usb.c @@ -106,7 +106,7 @@ struct ath6kl_usb_ctrl_diag_cmd_write { __le32 cmd; __le32 address; __le32 value; - __le32 _pad[1]; + DECLARE_FLEX_ARRAY(__le32, _pad); } __packed; struct ath6kl_usb_ctrl_diag_cmd_read { -- 2.34.1
