Subject: [PATCH 01/10] mmc: core: Add TRANsfer state to non-HPI state
Date: Sat, 18 Aug 2012 00:22:21 +0530	[thread overview]
Message-ID: <1345229550-8672-2-git-send-email-svenkatr@ti.com> (raw)
In-Reply-To: <1345229550-8672-1-git-send-email-svenkatr@ti.com>

HPI can be issued only in programming state to bring the card to
transfer state. If the card is already in transfer state, doing
a HPI is redundant.
Fix this by adding transfer state to the list of exceptions to
doing HPI and return without error.
