Linux kernel source tree
f6ffe7f018
We should not be checking the return values from debugfs creation at all: the debugfs functions are designed to handle errors of previously called functions and just transparently abort the creation of debugfs entries when debugfs is disabled. If we check the return value and abort driver initialisation, we break the driver if debugfs is disabled (such as when booting with debugfs=off). Earlier versions of ath9k accidentally did the right thing by checking the return value, but only for NULL, not for IS_ERR(). This was "fixed" by the two commits referenced below, breaking ath9k with debugfs=off starting from the 6.6 kernel (as reported in the Bugzilla linked below). Restore functionality by just getting rid of the return value check entirely. Link: https://bugzilla.kernel.org/show_bug.cgi?id=219122 Fixes: |

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.
