From 06fc3b70f1dc9c53070fa63a528830f54afc3c38 Mon Sep 17 00:00:00 2001 From: Tony Lindgren <tony@atomide.com> Date: Mon, 2 Jun 2014 16:13:46 -0700 Subject: [PATCH] gpio: of: Fix handling for deferred probe for -gpio suffix Commit dd34c37aa3e (gpio: of: Allow -gpio suffix for property names) added parsing for both -gpio and -gpios suffix but also changed the handling for deferred probe unintentionally. Because of the looping the second name will now return -ENOENT instead of -EPROBE_DEFER. Fix the issue by breaking out of the loop if -EPROBE_DEFER is encountered.
