The case ACPI_RESOURCE_TYPE_EXTENDED_IRQ inside acpi_pci_link_set()
is correctly using resource->res.data.extended_irq.foo for most settings,
but for the sharable setting it sofar has accidentally been using
resource->res.data.irq.shareable instead of
resource->res.data.extended_irq.shareable.

Note that the old code happens to also work because the sharable field
offset is the same for both the acpi_resource_irq and
acpi_resource_extended_irq structs.

s/sharable/shareable/ several times above
s/sofar/so far/

Thanks, I'll send out a v2 with the spelling issues in the commit-msg fixed.

Regards,

Hans

Ouch, looks like that copy/paste error has been there since the
beginning of git.  Nice catch!

  		resource->res.data.extended_irq.interrupt_count = 1;
  		resource->res.data.extended_irq.interrupts[0] = irq;
