[PATCH 29/39] pinctrl: Bulk conversion to generic_handle_domain_irq()

From: Marc Zyngier
Date: Thu May 20 2021 - 12:57:26 EST

Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().
