When CONFIG_DEBUGFS is enabled, we get a warning about an incorrect section annotation that can lead to undefined behavior: WARNING: vmlinux.o(.text+0xd3c7c4): Section mismatch in reference from the function mipi_csis_probe() to the function .init.text:mipi_csis_debugfs_init() The function mipi_csis_probe() references the function __init mipi_csis_debugfs_init(). This is often because mipi_csis_probe lacks a __init annotation or the annotation of mipi_csis_debugfs_init is wrong. The same function for an unknown reason has a different version for !CONFIG_DEBUGFS, which does not have this problem, but behaves the same way otherwise (it does nothing when debugfs is disabled). Consolidate the two versions, using the correct section from one version, and the implementation from the other.

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.
