Subject: [net-next 02/15] net/mlx5e: Replace zero-length arrays with DECLARE_FLEX_ARRAY() helper
Date: Tue, 29 Nov 2022 21:11:39 -0800	[thread overview]
Message-ID: <20221130051152.479480-3-saeed@kernel.org> (raw)
In-Reply-To: <20221130051152.479480-1-saeed@kernel.org>

From: "Gustavo A. R. Silva" <gustavoars@kernel•org>

Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length arrays
declarations in anonymous union with the new DECLARE_FLEX_ARRAY()
helper macro.

This helper allows for flexible-array members in unions.
