Certain Micron eMMC 4.5 cards might get broken when HPI feature is used and hence this patch disables the HPI feature for such buggy cards. The patch was needed on an i.MX6 to avoid HPI issues with that emmc card. Tested on a highly modified v3.14 kernel. It applies on top of the similar mainlined patch ported by Dirk Behme and delivered in v4.8: 5320226 mmc: core: Disable HPI for certain Hynix eMMC cards The baseline for this patch is: https://git.kernel.org/pub/scm/linux/kernel/git/ulfh/mmc.git/commit/?h=next&id=611d059f1a136dcb76a68eb715dc5c66d8a0a3fd "Merge branch 'fixes' into next" on the "next" branch, based on kernel v4.16-rc4.
