New Revision: 267762
URL: http://svnweb.freebsd.org/changeset/base/267762
Log:
Restore the check for non-NULL dmatag in sndbuf_free.
The sound drivers that use own buffer management can use sndbuf_setup
and not do any busdma allocation, so the driver will end up with the
managed buffer but no valid dma map and tag for it. Avoid calling
bus_dmamem_free in such cases.
