Subject: [PATCH v3 1/2] mwifiex: Use a define for firmware version string length
Date:   Wed,  3 Nov 2021 18:10:54 +0100
Message-Id: <20211103171055.16911-2-verdre@v0yd.nl>
In-Reply-To: <20211103171055.16911-1-verdre@v0yd.nl>

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Precedence: bulk

Since the version string we get from the firmware is always 128
characters long, use a define for this size instead of having the number
128 copied all over the place.
