vt8500_irq_mask() really does the ACK for edge triggered interrupts and the MASK for level triggered interrupts. Edge triggered interrupts never really are masked as a result, and there is unnecessary reading of the status register before the ACK even though it's write-one-to-clear. Split it up into a proper standalone vt8500_irq_ack() and an unconditional vt8500_irq_mask(). No Fixes tag added, as it has survived this way for 15 years and nobody complained, so apparently nothing really used edge triggered interrupts anyway.

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.
