From eb7f1c8415bbbb81f8674a490a5da7c22599a012 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 19 Oct 2025 10:31:38 +0200 Subject: [PATCH] gpio: mvebu: Slightly optimize mvebu_gpio_irq_handler() In the main loop of mvebu_gpio_irq_handler() some calls to irq_find_mapping() can be saved. There is no point to find an irq number before checking if this something has to be done. By testing first, some calls can be saved.
