Subject: [RFC V3 3/4] mmc: dw_mmc: move the platform specific init call
Date: Wed, 28 Aug 2013 17:38:50 +0530	[thread overview]
Message-ID: <1377691731-7226-4-git-send-email-yuvaraj.cd@samsung.com> (raw)
In-Reply-To: <1377691731-7226-1-git-send-email-yuvaraj.cd@samsung.com>

Current platform specific private data initialisation call
dw_mci_exynos_priv_init can be used to do platform specific
initialisation of SMU and others in future.So the drv_data->init
call has moved to dw_mci_probe.

changes since V2: none
changes since V1: none
