[PATCH 6.6 028/269] mmc: cqhci: Fix checking of CQHCI_HALT state

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

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

From: Seunghwan Baek <sh8267.baek@xxxxxxxxxxx>

commit aea62c744a9ae2a8247c54ec42138405216414da upstream.

To check if mmc cqe is in halt state, need to check set/clear of CQHCI_HALT
bit. At this time, we need to check with &, not &&.

Fixes: a4080225f51d ("mmc: cqhci: support for command queue enabled host")
