Subject: linux-next: build warnings after merge of the sound tree

Hi all,

After merging the sound tree, today's linux-next build (htmldocs)
produced these warnings:

sound/core/memalloc.c:203: warning: Function parameter or member 'mode' not described in 'snd_dma_buffer_sync'
sound/core/memalloc.c:203: warning: Excess function parameter 'mod' description in 'snd_dma_buffer_sync'

Introduced by commit

  a25684a95646 ("ALSA: memalloc: Support for non-contiguous page allocation")

Also, the declaration of this function in include/ound/memalloc.h looks
incorrect as it has different declarations depending on CONFIG_HAS_DMA, but
then another one afterwards.  I expect this will cause errors if
CONFIG_HAS_DMA is not set.
