Subject: [PATCH 2/3] mmc: sdhci-pci: Remove MMC_CAP_BUS_WIDTH_TEST for Intel controllers
Date: Fri, 20 May 2016 10:33:47 +0300 [thread overview]
Message-ID: <1463729628-3517-3-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1463729628-3517-1-git-send-email-adrian.hunter@intel.com>
The CMD19/CMD14 bus width test has been found to be unreliable in
some cases. It is not essential, so simply remove it.
