Refactor the mpic_handle_msi_irq() function to make it simpler: - drop the function arguments, they are not needed - rename the variable holding the doorbell cause register to "cause" - rename the iterating variable to "i" - use for_each_set_bit() (requires retyping "cause" to unsigned long) Signed-off-by: Marek Behún <kabel@kernel.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Link: https://lore.kernel.org/all/20240711115748.30268-10-kabel@kernel.org
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.
