smatch warnings: drivers/crypto/stm32/stm32-crc32.c:108 stm32_crc_get_next_crc() warn: can 'crc' even be NULL? Use list_first_entry_or_null instead of list_first_entry to retrieve the first device registered. The function list_first_entry always return a non NULL pointer even if the list is empty. Hence checking if the pointer returned is NULL does not tell if the list is empty or not.

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.
