make KCFLAGS='-fanalyzer' sound/soc/intel/atom/ reports a possible NULL pointer dereference. sound/soc/intel/atom/sst/sst_stream.c:221:40: error: dereference of NULL ‘block’ [CWE-476] [-Werror=analyzer-null-dereference] 221 | unsigned char *r = block->data; This is a false-positive, the GCC analyzer generated that report by considering if (bytes->block) as true in some cases and false in others. We can simplify the code and use a local variable so that static analysis does not try to look for cases where bytes->block can be modified concurrently.

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.
