GCC 12 seems upset that we check ipa_irq against array bound
but then proceed, anyway:
drivers/net/ipa/ipa_interrupt.c: In function ‘ipa_interrupt_add’:
drivers/net/ipa/ipa_interrupt.c:196:27: warning: array subscript 30 is above array bounds of ‘void (*[30])(struct ipa *, enum ipa_irq_id)’ [-Warray-bounds]
196 | interrupt->handler[ipa_irq] = handler;
| ~~~~~~~~~~~~~~~~~~^~~~~~~~~
drivers/net/ipa/ipa_interrupt.c:42:27: note: while referencing ‘handler’
42 | ipa_irq_handler_t handler[IPA_IRQ_COUNT];
| ^~~~~~~
