Subject: [PATCH -next] crypto: algboss - Replaced simple_strtol() with kstrtouint()
Date:   Mon, 24 May 2021 20:08:34 +0800
Message-ID: <20210524120834.1580343-1-liushixin2@huawei.com>

Precedence: bulk

The simple_strtol() function is deprecated in some situation since
it does not check for the range overflow. Use kstrtouint() instead.
