X-Git-Tag: v2.6.39-rc1~218
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4061d68e1a59ffacdf216a55f254cb01d4d1f840;p=pandora-kernel.git

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.
