Samuel Ortiz cd48d8ba14 NFC: microread: Fix mei physical layer
The MEI bus API changed according to the latest comments from the char-misc
maintainers, and this patch fixes the microread mei physical layer code
according to those changes:
We pass the MEI id back to the probe routine, and the mei_driver takes a
table of MEI ids instead of one static id.
Also, mei_bus_driver got renamed to mei_driver, mei_bus_client to
mei_device, and mei_bus_set/get_clientdata to mei_set/get_clientdata.

A secure element link can be enabled and disabled, and card emulation will

Eric Lapuyade 40d06d3647 NFC: Changed event_received hci ops result semantic
Some chips use a standard HCI event code, destined to a proprietary
gate, with a different meaning. Therefore, the HCI driver must always
have a chance to intercept the event before standard processing is
attempted.
The new semantic specifies that the result value "1" means that the
driver doesn't especially handle the event. result <= 0 means it was
handled.

It is intended to replace pn533_send_cmd_frame_sync() iface which
requires from the caller to create complete frame.

The new function constructs a complete frame itself and sends it out
in sync manner. This way frame logic is hidden from the caller.

pn533_send_cmd_sync() returns ERR_PTR in case of an error or a pointer
to valid response sk_buff otherwise. The pointer must be freed by the
caller when it's been consumed.

This is intendend to replace pn533_send_cmd_frame_async() which
requires from the caller to create a complete frame.

The new function constructs a frame and sends it out which hides the
frame logic and avoid code duplication.

The caller has to allocate skb and put its payload there, and finally
provide the skb together with a complete cb to pn533_send_cmd_async().

Response skb is allocated by the core part and pass to the caller cb.
Next, the caller has to free it when is not needed anymore or pass it
up to the stack.

Greg Kroah-Hartman 0fe763c570 Drivers: misc: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
