Subject: ARM: at91: fix external interrupts in non-DT case
From: Nicolas Ferre <[email protected]>
commit 738a0fd752dc60e20beeda6f2f0f62e58dc0e344 upstream.
Management of external interrupts has changed but the
non-DT code has not integrated these changes.
Add a mask to pass external irq specification from SoC
specific code to the at91_aic_init() function.
