Subject: [PATCH 534/806] mmc: sdhci: Mask "spurious" interrupts
|
|
|
|
Add a filter for "spurious" Transfer Complete interrupts, attempting
|
|
to make it as specific as possible:
|
|
* INT_DATA_END (transfer complete) is set
|
|
* There is a stop command in progress
|
|
* There is no data transfer in progress
|
|
