[PATCH 0/2] mmc: cqhci: Spurious TCN fix

From: Kornel Dulęba

Hi Adrian,

This series contains a fix for the "spurious TCN" issue that happens
during CQE recovery. We discussed this problem in the:
"[PATCH] mmc: cqhci: Be more verbose in error irq handler" thread.
The fix implemented in the form of a quirk, that is applied to the JSL
controller only. This was done this way, since I believe that this is a
hardware issue. Note that this quirk might be applicable to controllers
on other Intel SoCs too.
Please let me know what do you think.

Regards,
Kornel
