[PATCH 4.4 38/41] ARM: pxa: fix the number of DMA requestor lines

From: Greg Kroah-Hartman
Date: Tue Oct 03 2017 - 09:11:25 EST


4.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Robert Jarzmik <robert.jarzmik@xxxxxxx>

commit 4c35430ad18f5a034302cb90e559ede5a27f93b9 upstream.

The number of requestor lines was clamped to 0 for all pxa architectures
in the requestor declaration. Fix this by using the value.
