[PATCH 2/2] mmc : fix for check cqe halt.

[Seunghwan Baek]

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 &&. Therefore, code to
check whether cqe is in halt state is modified to cqhci_halted, which has
already been implemented.

Fixes: 0653300224a6 ("mmc: cqhci: rename cqhci.c to cqhci-core.c")
