From 1e4d149e901769fcde71be039227d184c6e4fda9 Mon Sep 17 00:00:00 2001 From: "Ooi, Joyce" Date: Thu, 9 Jan 2020 00:16:20 +0800 Subject: [PATCH] gpio: altera: change to platform_get_irq_optional to avoid false-positive error This patch switches to platform_get_irq_optional() from platform_get_irq() as it causes a false-positive error such as 'IRQ index 0 not found' when IRQ is not used. The IRQ usage is optional in this gpio-altera driver, so the error log is undesirable.
