itimer_delete() uses spin_lock_irqsave() to obtain a `flags' variable which can then be passed to unlock_timer(). It uses already spin_lock locking for the structure instead of lock_timer() because it has a timer which can not be removed by others at this point. The cleanup is always performed with enabled interrupts. Use spin_lock_irq() / spin_unlock_irq() so the `flags' variable can be removed.

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.
