Arnaldo Carvalho de Melo 28e898ffa0 tools include UAPI: Sync the sound/asound.h copy with the kernel sources 
Picking the changes from:

  01dfa8e969 ("ALSA: ump: Add info flag bit for static blocks")
  e375b8a045 ("ALSA: ump: Add more attributes to UMP EP and FB info")
  30fc139260 ("ALSA: ump: Add ioctls to inquiry UMP EP and Block info via control API")
  127ae6f6da ("ALSA: rawmidi: Skip UMP devices at SNDRV_CTL_IOCTL_RAWMIDI_NEXT_DEVICE")
  e3a8a5b726 ("ALSA: rawmidi: UMP support")
  a4bb75c4f1 ("ALSA: uapi: pcm: control the filling of the silence samples for drain")

That harvests some new ioctls:

  $ tools/perf/trace/beauty/sndrv_ctl_ioctl.sh > before.ctl
  $ tools/perf/trace/beauty/sndrv_pcm_ioctl.sh > before.pcm
  $ cp include/uapi/sound/asound.h tools/include/uapi/sound/asound.h
  $ tools/perf/trace/beauty/sndrv_ctl_ioctl.sh > after.ctl
  $ tools/perf/trace/beauty/sndrv_pcm_ioctl.sh > after.pcm

Now those will be decoded when they appear, see a system wide 'perf
trace' session example here:

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
