commit2de860b4a7upstream. As platform_get_irq_byname() now prints an error when the interrupt does not exist, scary warnings may be printed for optional interrupts: renesas_spi e6b10000.spi: IRQ rx not found renesas_spi e6b10000.spi: IRQ mux not found Fix this by calling platform_get_irq_byname_optional() instead. Remove the no longer needed printing of platform_get_irq errors, as the remaining calls to platform_get_irq() and platform_get_irq_byname() take care of that.

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.
