Subject: [PATCH 01/11] extcon: arizona: Disable debouce for accessory removal detection
Date: Mon, 11 Feb 2013 16:26:56 +0000 [thread overview]
Message-ID: <1360600026-16878-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <20130211162614.GH4607@opensource.wolfsonmicro.com>
Ensure we clamp as quickly as possible after removal by disabling the
debounce while there is an accessory present.
