Subject: [PATCH 2/7] extcon: arizona: Fix reset of HPDET after race with removal
Date: Wed, 13 Nov 2013 18:04:32 +0000	[thread overview]
Message-ID: <1384365877-12355-2-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1384365877-12355-1-git-send-email-ckeepax@opensource.wolfsonmicro.com>

We need to make sure we reset back to our starting state, especially
making sure that we have disabled poll in the register cache.
