Takashi Iwai 5a494fdbfc ALSA: ump: Transmit RPN/NRPN message at each MSB/LSB data reception
[ Upstream commit e6ce8a28c768dbbad3f818db286cd0f4c7a921a8 ]

The UMP 1.1 spec says that an RPN/NRPN should be sent when one of the
following occurs:
* a CC 38 is received
* a subsequent CC 6 is received
* a CC 98, 99, 100, and 101 is received, indicating the last RPN/NRPN
  message has ended and a new one has started

That said, we should send a partial data even if it's not fully
filled.  Let's change the UMP conversion helper code to follow that
rule.

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.
