From: Shuah Khan Date: Sat, 3 Nov 2012 23:00:07 +0000 (-0600) Subject: dma-debug: fix to not have dependency on get_dma_ops() interface X-Git-Tag: v3.8-rc1~25^2^2~10 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bfe0fb0f1a570ae72680d6d48655c98d1f4733f5;p=pandora-kernel.git dma-debug: fix to not have dependency on get_dma_ops() interface dma-debug depends on get_dma_ops() interface. Several architectures do not define dma_ops and get_dma_ops(). When dma debug interfaces are used on an architecture (e.g: c6x) that doesn't define get_dmap_ops(), compilation fails. Changing dma-debug to call dma_mapping_error() instead of defining its own that calls get_dma_ops(), such that the internal use of dma_mapping_error() doesn't interfere with the debug_dma_mapping_error() interface's mapping error checks. Moving dma_mapping_error() checks in check_unmap() under the dma debug entry not found is sufficient to fix the problem.
