Subject: [PATCH 07/12] mmc: core: export the alive operation
Date: Thu, 9 Jun 2016 09:10:13 +0200 [thread overview]
Message-ID: <1465456218-28354-8-git-send-email-gregory.clement@free-electrons.com> (raw)
In-Reply-To: <1465456218-28354-1-git-send-email-gregory.clement@free-electrons.com>
Depending of the type of card there is a different operation to know
if the car is alive. However, the access to this operation are private.
This patch introduce a new function allowing to know if the card is alive
by using the appropriate operation.
