The in_interrupt() macro is ill-defined and does not provide what the name suggests. The usage especially in driver code is deprecated and a tree-wide effort to clean up and consolidate the (ab)usage of in_interrupt() and related checks is happening. In this case the check covers only parts of the contexts in which these functions cannot be called. It fails to detect preemption or interrupt disabled invocations. As wait_for_completion() already contains a broad variety of checks (always enabled or debug option dependent) which cover all invalid conditions already, there is no point in having extra inconsistent warnings in drivers. Just remove it.

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.
