From 2f7bb2dfed3b15b388c88250b66f590aabc438da Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 17 Dec 2009 14:25:10 +0900 Subject: [PATCH] sh: Fix up MAX_DMA_CHANNELS definition when DMA is disabled. MAX_DMA_CHANNELS is tested for the total number of channels in order to populate an IRQ map. Stub this out completely when no DMA support is enabled -- as used to be the default behaviour before this was generalized for use by the dmaengine code.
