From: Nicolas Pitre <nicolas.pitre@linaro.org>
commit c1c90728efa49eab81ae816718d84116a22b790e upstream.
Commit 5d6bed2a9c ("ARM: dove: fix legacy dove IRQ numbers") shifted
IRQ numbers by one but didn't update the get_irqnr_and_base macro
accordingly. This macro is involved when CONFIG_MULTI_IRQ_HANDLER
is not defined.
[jac: 5d6bed2a9c went in to v4.2, but was backported to v3.18]
