Jon Hunter 8b3ae914e3 mailbox: tegra: Fix superfluous IRQ error message
commit c745da8d4320c49e54662c0a8f7cb6b8204f44c4 upstream.

Commit 7723f4c5ec ("driver core: platform: Add an error message to
platform_get_irq*()") added an error message to avoid drivers having
to print an error message when IRQ lookup fails. However, there are
some cases where IRQs are optional and so new optional versions of
the platform_get_irq*() APIs have been added for these cases.

The IRQs for Tegra HSP module are optional because not all instances
of the module have the doorbell and all of the shared interrupts.
Hence, since the above commit was applied the following error messages
are now seen on Tegra194 ...

 ERR KERN tegra-hsp c150000.hsp: IRQ doorbell not found
 ERR KERN tegra-hsp c150000.hsp: IRQ shared0 not found

The Tegra HSP driver deliberately does not fail if these are not found
and so fix the above errors by updating the Tegra HSP driver to use
the platform_get_irq_byname_optional() API.

README

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.
