Till now the Rockchip iommu driver walked through the irq list via
platform_get_irq() until it encountered an ENXIO error. With the
recent change to add a central error message, this always results
in such an error for each iommu on probe and shutdown.
To not confuse people, switch to platform_count_irqs() to get the
actual number of interrupts before walking through them.
Fixes: 7723f4c5ec ("driver core: platform: Add an error message to platform_get_irq*()")

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.
