Subject: [PATCH] mmc: dw_mmc: Handle DW_MCI_QUIRK_IDMAC_DTO properly
Date: Tue, 9 Jul 2013 13:04:40 -0700 [thread overview]
Message-ID: <1373400280-7408-1-git-send-email-dianders@chromium.org> (raw)
In (1fb5f68 mmc: dw_mmc: Don't loop when handling an interrupt), the
code for handling DW_MCI_QUIRK_IDMAC_DTO became dead code. Move it to
where it ought to live.
Found by code inspection and compile-tested only--I don't know of any
boards that need DW_MCI_QUIRK_IDMAC_DTO.
