From 827e1579e1d5cb66e340e7be1944b825b542bbdf 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 04ff5a095d66 ("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.
