Subject: [PATCH v3 12/14] dmaengine: pxa: make the filter function internal
Date: Sun, 17 Jun 2018 19:02:15 +0200	[thread overview]
Message-ID: <20180617170217.24177-13-robert.jarzmik@free.fr> (raw)
In-Reply-To: <20180617170217.24177-1-robert.jarzmik@free.fr>

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.
