4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Christoph Fritz <chf.fritz@xxxxxxxxxxxxxx> commit 91516a2a4734614d62ee3ed921f8f88acc67c000 upstream. To get an usdhc Apacer and some ATP SD cards work reliable, CMD23 needs to be disabled. This has been tested on i.MX6 (sdhci-esdhc) and rk3288 (dw_mmc-rockchip).
