Subject: [PATCH 1/2] ARM: davinci: make the function argument as const
Date:   Mon, 16 Oct 2017 12:08:23 +0200
Message-Id: <1508148504-2771-2-git-send-email-bhumirks@gmail.com>
In-Reply-To: <1508148504-2771-1-git-send-email-bhumirks@gmail.com>
References: <1508148504-2771-1-git-send-email-bhumirks@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Make the function argument of the function davinci_common_init
as const as it's memory contents are only copied during a
memcpy call. So, the fields of the structure to which the argument
soc_info points to never gets modified and therefore the argument can
be made const.
Add const to the prototype too.
