R. Silva" <gustavoars@...nel.org>, linux-hardening@...r.kernel.org Subject: [PATCH][next] carl9170: Replace zero-length array with DECLARE_FLEX_ARRAY() helper 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.
