Subject: [PATCH v7 11/12] rpmsg: Constify local variable in field store macro
Date:   Tue, 19 Apr 2022 13:34:34 +0200
Message-Id: <20220419113435.246203-12-krzysztof.kozlowski@linaro.org>
In-Reply-To: <20220419113435.246203-1-krzysztof.kozlowski@linaro.org>
References: <20220419113435.246203-1-krzysztof.kozlowski@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Memory pointed by variable 'old' in field store macro is not modified,
so it can be made a pointer to const.
