mei: fix reading large reposnes

2013-04-19T20:38:38+00:00

While writting to device is limitted to max_msg_length advertized
in client properites the read can be much longer delivered consequiting chunks.

We use krealloc to enlarge the buffer when needed.

mei: nfc: Initial nfc implementation

2013-04-11T01:56:53+00:00

NFC ME device is exported through the MEI bus to be consumed by the
NFC subsystem.

NFC is represented by two mei clients: An info one and the actual
NFC one. In order to properly build the ME id we first need to retrieve
the firmware information from the info client and then disconnect from it.

we rename the mei_host_buffer_is_empty to keep naming
convention of hbuf and also make the query more generic
to be correct also for other under laying hardware

mei: drop the warning when cl is not initialized during unlinking

2013-01-14T16:26:03+00:00

On systems where wd and amthif is not initialized
we will hit cl->dev == NULL. This condition is okay
so we don't need to be laud about it.

Fixes the follwing warning during suspend

mei: normalize me host client linking routines

2013-01-09T00:40:46+00:00

In order we can use the same code pattern for in-kernel
and user space host clients we replace mei_cl_link_to_me
with mei_cl_link function.
We then have to keep me client lookupout of the new link function.

The unlinking cannot be yet symetric due to amthif connection
handling
