From e0c73835f5aed5124f7d8c04717fd1490cf0bf3a 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 da4fe7e53b7c ("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.
