container_of() cannot return NULL, so the checks for NULL pointers are unnecessary and can be safely removed. As a result, this commit silences the following smatch warnings: coresight-stm.c:345 stm_generic_link() warn: can 'drvdata' even be NULL? coresight-stm.c:356 stm_generic_unlink() warn: can 'drvdata' even be NULL? coresight-stm.c:387 stm_generic_set_options() warn: can 'drvdata' even be NULL? coresight-stm.c:422 stm_generic_packet() warn: can 'drvdata' even be NULL?

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.
