Subject: Re: [PATCH] iommu/ipmmu-vmsa: Only call platform_get_irq() when interrupt is mandatory

Quoting Geert Uytterhoeven (2019-10-01 11:06:22)
> As platform_get_irq() now prints an error when the interrupt does not
> exist, calling it gratuitously causes scary messages like:
> 
>     ipmmu-vmsa e6740000.mmu: IRQ index 0 not found
> 
> Fix this by moving the call to platform_get_irq() down, where the
> existence of the interrupt is mandatory.
