Merge series from Cezary Rojewski <cezary.rojewski@intel.com>: Medium range of fixes all avs-driver related. The most important fixes lead the way: 1. For ASoC-hda codec driver, existing RPM manipulation in hda_codec_probe_complete()'s error path is superfluous and leads to RPM usage count underflow if the probe exists early e.g.: build-controls operation fails. 2. Resolve deadlock when DSP-recovery is a consequence of SET_D0IX IPC. The procedure handling IPC timeouts and EXCEPTION_CAUGHT notification shall cancel any D0IX work before proceeding with DSP recovery. If SET_D0IX called from delayed_work is the failing IPC the procedure will deadlock. 3. LINK format (PPLCxFMT) calculation is incorrect. HDAudio transfer types utilize SDxFMT for front-end (HOST) and PPLCxFMT for back-end (LINK) side when setting up the stream. BE's substream->runtime duplicates FE runtime so switch to using BE's hw_params to address incorrect format values on the LINK side when FE and BE formats differ. Below three patches address problems found by Coverity static analyzer: ASoC: Intel: avs: Fix possible null-ptr-deref when initing hw ASoC: Intel: avs: Verify kcalloc() status when setting constraints ASoC: Intel: avs: Verify content returned by parse_int_array() While unlikely in runtime, it's good to keep code resilient. The last few patches are readability/cohesiveness improvements.
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 reStructuredText 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.
