From 58fb7c643d346e2364404554f531cfa6a1a3917c Mon Sep 17 00:00:00 2001 From: Sergey Shtylyov Date: Sun, 4 Jul 2021 17:38:45 +0300 Subject: i2c: mt65xx: fix IRQ check Iff platform_get_irq() returns 0, the driver's probe() method will return 0 early (as if the method's call was successful). Let's consider IRQ0 valid for simplicity -- devm_request_irq() can always override that decision...
