mei: amthif: discard not read messages

2016-06-01T19:16:59Z

commit 9d04ee11db7bf0d848266cbfd7db336097a0e239 upstream. When a message is received and amthif client is not in reading state the message is ignored and left dangling in the queue. This may happen after one of the amthif host connections is closed w/o completing the reading. Another client will pick up a wrong message on next read attempt which will lead to link reset. To prevent this the driver has to properly discard the message when amthif client is not in reading state.

debugfs: Pass bool pointer to debugfs_create_bool()

2015-10-04T10:36:07Z

Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.

mei: bus: add and call callback on notify event

2015-08-04T00:30:00Z

Enable drivers on mei client bus to subscribe to asynchronous event notifications. Introduce events_mask to the existing callback infrastructure so it is possible to handle both RX and event notification.
