At dpcm_be_dai_startup_unwind(), it indicates error message at (1)
if this function was called with no users.
But, it doesn't use "continue" here. Thus, users will be a
negative number at (2)
void dpcm_be_dai_startup_unwind(...)
{
...
for_each_dpcm_be(...) {
...
(1) if (be->dpcm[stream].users == 0)
dev_err(...);
(2) if (--be->dpcm[stream].users != 0)
continue;
At dpcm_be_dai_startup(), it indicates error message if
user reached to MAX USERS at (A).
But, it doesn't use "continue" here. Thus, it will be over
MAX USERS at (B).
int dpcm_be_dai_startup(...)
{
...
for_each_dpcm_be(...) {
...
(A) if (be->dpcm[stream].users == DPCM_MAX_BE_USERS)
dev_err(...);
(B) if (be->dpcm[stream].users++ != 0)
continue;
These are just bug. This patch fixup these.

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.
