Subject: [PATCH v3 12/14] dmaengine: pxa: make the filter function internal
Date:   Sun, 17 Jun 2018 19:02:15 +0200
Message-Id: <20180617170217.24177-13-robert.jarzmik@free.fr>
In-Reply-To: <20180617170217.24177-1-robert.jarzmik@free.fr>
References: <20180617170217.24177-1-robert.jarzmik@free.fr>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

As the pxa architecture and all its related drivers do not rely anymore
on the filter function, thanks to the slave map conversion, make
pxad_filter_fn() static, and remove it from the global namespace.
