Subject: [PATCH 06/12] mmc: core: Extend shutdown sequence to handle bus operations
Date: Mon, 10 Jun 2013 17:03:41 +0200	[thread overview]
Message-ID: <1370876627-13439-7-git-send-email-ulf.hansson@stericsson.com> (raw)
In-Reply-To: <1370876627-13439-1-git-send-email-ulf.hansson@stericsson.com>

From: Ulf Hansson <ulf.hansson@linaro.org>

By adding an optional .shutdown callback to the bus_ops struct we
provide the possibility to let each bus type handle it's shutdown
requirements.
