commit a3cab1d2132474969871b5d7f915c5c0167b48b0 upstream.
With the current logic the "failed to exit halt state" error would be shown even if any other bit than CQHCI_HALT was set in the CQHCI_CTL register, since the right hand side is always true. Fix this by using the correct operator (bit-wise instead of logical AND) to only check for the halt bit flag, which was obviously intended here.
