spin_trylock_irqsave() has a __cond_lock() wrapper which points to __spin_trylock_irqsave(). The function then invokes spin_trylock() which has another __cond_lock() finally pointing to rt_spin_trylock(). The compiler has no problem to parse this but sparse does not recognise that users of spin_trylock_irqsave() acquire a conditional lock and complains. Remove one layer of __cond_lock() so that sparse recognises conditional locking.

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.
