From 9e238e380c2a8aff21d37f713b5c24b079a726a5 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 31 Aug 2017 07:58:17 +0200 Subject: Revert "gpiolib: request the gpio before querying its direction" This reverts commit 108d23e322a247d9f89ba2e2742520ead0944cc9. It turns out this causes a regression on the OMAP, Marvell and Renesas.
