From 832392db9747b9c95724d37fc6a5dadd3d4ec514 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Fri, 11 Oct 2019 13:22:58 +0300 Subject: [PATCH] platform/x86: i2c-multi-instantiate: Fail the probe if no IRQ provided For APIC case of interrupt we don't fail a ->probe() of the driver, which makes kernel to print a lot of warnings from the children. We have two options here: - switch to platform_get_irq_optional(), though it won't stop children to be probed and failed - fail the ->probe() of i2c-multi-instantiate Since the in reality we never had devices in the wild where IRQ resource is optional, the latter solution suits the best.
