R. Silva" <gustavoars@...nel.org>, linux-hardening@...r.kernel.org Subject: [PATCH][next] can: etas_es58x: 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 array declaration in union es58x_urb_cmd with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for a flexible-array member in a union.
