Quoting Geert Uytterhoeven (2019-10-16 07:31:01)
> 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.
