Date: Fri, 23 Jul 2021 11:20:34 +0200 From: Krzysztof Kozlowski <krzysztof.kozlowski@...onical.com> To: Krzysztof Kozlowski <krzysztof.kozlowski@...onical.com>, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH] nfc: port100: constify protocol list array File-scope "port100_protocol" array is read-only and passed as pointer to const, so it can be made a const to increase code safety.
