From 476d79f1427798deb5107ad142cdea7d46883b4a Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Tue, 9 Jul 2013 13:04:40 -0700 Subject: mmc: dw_mmc: Handle DW_MCI_QUIRK_IDMAC_DTO properly 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.
