Subject: [PATCH 9/9] mmc: dw_mmc: remove system PM callback
Date: Sun,  9 Oct 2016 21:51:11 +0800	[thread overview]
Message-ID: <1476021071-31477-1-git-send-email-shawn.lin@rock-chips.com> (raw)
In-Reply-To: <1476020951-31292-1-git-send-email-shawn.lin-TNX95d0MmH7DzftRWevZcw@public.gmane.org>

Now there are no variant drivers using dw_mci_suspend
and dw_mci_resume, so let's remove it.
