As platform_get_irq() now prints an error when the interrupt does not
exist, scary warnings may be printed for optional interrupts:
sh-sci e6550000.serial: IRQ index 1 not found
sh-sci e6550000.serial: IRQ index 2 not found
sh-sci e6550000.serial: IRQ index 3 not found
sh-sci e6550000.serial: IRQ index 4 not found
sh-sci e6550000.serial: IRQ index 5 not found
Fix this by calling platform_get_irq_optional() instead for all but the
first interrupts, which are optional.

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.
