Subject: [PATCH 1/3] mmc: tmio: add init_card ops
Date: Fri, 26 Apr 2019 14:18:48 +0900	[thread overview]
Message-ID: <1556255930-18188-2-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <1556255930-18188-1-git-send-email-yoshihiro.shimoda.uh@renesas.com>

Since renesas_sdhi_internal_dmac driver would like to use
the init_card() ops in the future, this patch adds init_card ops
into the struct tmio_mmc_host and struct tmio_mmc_dma_ops.
