mei: bus: fix received data size check in NFC fixup

2016-10-31T16:25:22+00:00

NFC version reply size checked against only header size, not against
full message size. That may lead potentially to uninitialized memory access
in version data.

That leads to warnings when version data is accessed:
drivers/misc/mei/bus-fixup.c: warning: '*((void *)&ver+11)' may be used uninitialized in this function [-Wuninitialized]:  => 212:2

mei: bus: use mei_cldev_ prefix for the API functions

2015-09-21T02:31:10+00:00

Use mei_cldev_ prefix for all mei client bus api functions
in order to resolve prefix conflict with functions that handle
client function and are defined in client.c

mei: bus: complete variable rename of type struct mei_cl_device

2015-09-21T02:31:09+00:00

In the
commit 5c079ae11921 ("mei: bus: fix drivers and devices names confusion")
we set the variables of type struct mei_cl_device to 'cldev'
but few places were left out, namely mei_cl_bus.h header
and the mei nfc drivers.

mei: bus: add and call callback on notify event

2015-08-04T00:30:00+00:00

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.

NFC: mei_phy: adjust mei nfc header according the spec

2015-05-24T18:15:54+00:00

1. mei_nfc_hci_hdr and mei_nfc_hdr are just the same thing so drop one
2. use mei_nfc_hdr structure as the member of the command and the reply
instead of replicating all header fields.
3. dump the header for easier debugging

NFC: mei_phy: move all nfc logic from mei driver to nfc

2015-05-24T18:15:54+00:00

move nfc logic to mei_phy module, we prefer as much as
possible not to deal with a particualr client protocol
in the mei generic infrasutcutre
