Kernel coding style expects all drivers to ignore debugfs errors. Partially because it is purely for debugging, not for important user interfaces. Simplify the code by dropping unnecessary probe failuring and error message on debugfs failures, which also fixes incorrect usage IS_ERR_OR_NULL() and Smatch warning: drivers/soc/tegra/cbb/tegra-cbb.c:80 tegra_cbb_err_debugfs_init() warn: passing zero to 'PTR_ERR' Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20250104141958.115911-1-krzysztof.kozlowski@linaro.org Signed-off-by: Thierry Reding <treding@nvidia.com>
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.
