Subject: [PATCH 10/12] nfc: microread: constify several pointers
Date: Thu, 29 Jul 2021 12:40:20 +0200 [thread overview]
Message-ID: <20210729104022.47761-11-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210729104022.47761-1-krzysztof.kozlowski@canonical.com>
Several functions do not modify pointed data so arguments and local
variables can be const for correctness and safety.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>
