Subject: [PATCH AUTOSEL 6.1 10/24] pinctrl: amd: Fix debug output for debounce time

From: Mario Limonciello <mario.limonciello@....com>

[ Upstream commit c6e0679b8381bf03315e6660cf5370f916c1a1c6 ]

If one GPIO has debounce enabled but future GPIOs in the list don't
have debounce the time never gets reset and shows wrong value.
