This does no harm unless one of the functions requesting the IRQ fails and attempt to free the IRQ. This may end up with a warning from the IRQ core that is expecting the affinity hint to be cleared before freeing the IRQ: kernel/irq/manage.c: /* make sure affinity_hint is cleaned up */ if (WARN_ON_ONCE(desc->affinity_hint)) desc->affinity_hint = NULL; So to fix this, let's set the IRQ affinity hint after requesting all the shared IRQ. This will make sure that the affinity hint gets cleared in the error path before freeing the IRQ.
