Problem Description: HTML and other documentation in not generated from DocBook files found in Documentation/sound/alsa/DocBook/ since there is no Makefile for them. The most logical solution is to move the 2 files in Documentation/DocBook/ and add them to the relative Makefile.
Done. Patch is at http://oss.oracle.com/~rdunlap/patches/docbook-move-alsa-docs.patch
The patch can't be applied to the latest sound git tree, unfortunately. Could you rebase the patch against it? git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
Please try this new patch: http://oss.oracle.com/~rdunlap/patches/docbook-move-alsa-docsv2.patch
Thanks, applied now. Should appear in the next linux-next tree.
