From 822969369482166050c5b2f7013501505e025c39 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 20 May 2016 10:33:47 +0300 Subject: [PATCH] mmc: sdhci-pci: Remove MMC_CAP_BUS_WIDTH_TEST for Intel controllers The CMD19/CMD14 bus width test has been found to be unreliable in some cases. It is not essential, so simply remove it.
