Subject: [PATCH 2/6] soc: mediatek: mtk-svs: Switch to platform_get_irq()
Date:   Tue, 26 Jul 2022 16:16:49 +0200

Instead of using irq_of_parse_and_map() to retrieve the interrupt from
devicetree, switch to platform_get_irq() instead: this function will
conveniently also write an error message in case the irq is not found.
