Subject: [PATCH 06/12] mmc: tmio: Mask all IRQs when inactive
Date: Mon, 25 Aug 2014 14:25:58 +0200 [thread overview]
Message-ID: <1408969564-6335-7-git-send-email-ulf.hansson@linaro.org> (raw)
In-Reply-To: <1408969564-6335-1-git-send-email-ulf.hansson@linaro.org>
To make sure we don't receive any spurious IRQs while we are inactive,
mask the IRQs from within the ->runtime_suspend() callback.
