From 8604ac34eb19f7b02f8cf22c787fe30d96ad2651 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 20 Nov 2012 14:42:47 +0100 Subject: [PATCH] pinctrl/u300/coh901: stop spawning pinctrl from GPIO Let's stop spawning the pinctrl driver from the GPIO driver, we have these two mechanisms broken apart now, and they can each probe in isolation. If the GPIO driver cannot find its pin controller (pinctrl-u300), the pin controller core will tell it to defer probing.
