From fce1442164cff51250c8f264b3757fd76f2a955b Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 26 Jan 2016 13:41:20 +0000 Subject: [PATCH] mmc: sdhci: further code simplication Further simplify the code in sdhci_prepare_data() - we don't set SDHCI_REQ_USE_DMA anywhere else in the driver, so there is no need to set it, and then immediately test it.
