Subject: [PATCH 1/2] CLK: SPEAr: make structure field and function argument as const
Date:   Tue, 17 Oct 2017 16:38:33 +0200
Message-Id: <1508251114-7042-2-git-send-email-bhumirks@gmail.com>
In-Reply-To: <1508251114-7042-1-git-send-email-bhumirks@gmail.com>
References: <1508251114-7042-1-git-send-email-bhumirks@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Make the masks field of clk_aux structure const as it do not modify the
fields of the aux_clk_masks structure it points to.

Make the struct aux_clk_masks *aux argument of the function
clk_register_aux as const as the argument is only stored in the masks
field of a clk_aux structure which is now made const.
