X-Git-Tag: v2.6.25-rc6~16^2~4 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9b941c6660bae673e27c207f1d20d98ef8ecd450;p=linux-2.6 dmaengine: Fix a bug about BUG_ON() on DMA engine capability DMA_INTERRUPT. The device->device_prep_dma_interrupt function is used by DMA_INTERRUPT capability, not DMA_ZERO_SUM.
