Subject: [PATCH AUTOSEL 5.10 05/21] tools: gpio: fix debounce_period_us output of lsgpio

From: Milo Spadacini <milo.spadacini@...il.com>

[ Upstream commit eb4b8eca1bad98f4b8574558a74f041f9acb5a54 ]

Fix incorrect output that could occur when more attributes are used and
GPIO_V2_LINE_ATTR_ID_DEBOUNCE is not the first one.
