Subject: [PATCH 0993/1085] drivers: mmc: cqhci: clear CQHCI_CTL if halt fails
|
|
|
|
The eMMC spec says that in certain circumstances the controller can't
|
|
respond to a halt request - in practice, this occurs if a CMD
|
|
timeout happens (card went away/crashed).
|
|
|
|
Clear the halt request by writing 0 to CQHCI_CTL. Also fix a logic error
|
|
testing for halt in cqhci_request.
