From d85757e305f48ace8c99ff9a6ffcb58692ac96c1 Mon Sep 17 00:00:00 2001 From: Joel Fernandes Date: Thu, 29 Aug 2013 18:05:45 -0500 Subject: [PATCH 5/5] dma: edma: Remove limits on number of slots

With this series, this check is no longer required and we shouldn't need to reject drivers DMA'ing more than the MAX number of slots.
