    Subject[PATCH 4.4 36/86] mmc: sdhci-pci: Remove MMC_CAP_BUS_WIDTH_TEST for Intel controllers
    Date
    4.4-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.
