Author: jhb Date: Tue Jun 17 16:07:57 2014 New Revision: 267581 URL: http://svnweb.freebsd.org/changeset/base/267581 Log: Fix various bugs with freeing static DMA allocations in sound drivers: - Don't compare the DMA map to NULL to determine if bus_dmamap_unload() should be called when releasing a static allocation. Instead, compare the bus address against 0. - Don't assume that the DMA map for static allocations is NULL. Instead, save the value set by bus_dmamem_alloc() so it can later be passed to bus_dmamem_free(). Also, add missing calls to bus_dmamap_unload() in these cases before freeing the buffer. - Use the bus address from the bus_dma callback instead of calling vtophys() on the address allocated by bus_dmamem_alloc().
