From 4061d68e1a59ffacdf216a55f254cb01d4d1f840 Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Tue, 22 Mar 2011 16:34:57 -0700 Subject: x86: only compile 8237A if CONFIG_ISA_DMA_API is enabled 8237A utilizes the interface provided by CONFIG_ISA_DMA_API, specifically claim_dma_lock() and release_dma_lock(). Thus, there's a strict dependency on the config option and the module should only be loaded if the kernel supports ISA-style DMA. Signed-off-by: David Rientjes Cc: Ingo Molnar Cc: "H.
