[PATCH 4.6 037/100] mmc: sdhci-pci: Remove MMC_CAP_BUS_WIDTH_TEST for Intel controllers

Show all headers | View raw

4.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Adrian Hunter <adrian.hunter@intel.com>

commit 822969369482166050c5b2f7013501505e025c39 upstream.

The CMD19/CMD14 bus width test has been found to be unreliable in
some cases.  It is not essential, so simply remove it.
