[PATCH] mmc: sdhci-pci-core: Disable cqe for ASUS 1100FK family devices

[Patrick Thompson]

From: ptf <ptf@xxxxxxxxxx>

The CQE implementation for the eMMC in the ASUS 1100FK family of devices
is broken. This causes installations to fail and thus we are disabling
CQE for this family of devices.

Hello,

I was hoping to get some advice on adapting this patch to target the
eMMC directly instead of a family of laptops. One idea is to use the
PCI-id of the controller (in this case [8086:4dc4]). Would that make
sense? Is there someone with more knowledge on the subject that could
confirm that the [8086:4dc4] device doesn't have a working CQE?

Thank you,
Patrick
