From 1a50191f7e51245bc6fd04c4df8bd0609f3d11f4 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 26 Jan 2017 19:24:07 +0200 Subject: [PATCH] pinctrl: baytrail: Rectify debounce support (part 2) The commit 03522c7c1856 ("pinctrl: baytrail: Rectify debounce support") almost fixes the logic of debuonce but missed couple of things, i.e. typo in mask when disabling debounce and lack of enabling it back. This patch addresses above issues.
