Alex Dubov f1d8269802 memstick: use fully asynchronous request processing
Instead of using a separate thread to pump requests from block layer queue
to memstick, do so inline, utilizing the callback design of the memstick.

Alex Dubov 17017d8d2c memstick: add "start" and "stop" methods to memstick device
In some cases it may be desirable to ensure that associated driver is not
going to access the media in some period of time.  "start" and "stop"
methods are provided therefore to allow it.

Alex Dubov b77899985b memstick: allow "set_param" method to return an error code
Some controllers (Jmicron, for instance) can report temporal failure
condition during power-on.  It is desirable to account for this using a
return value of "set_param" device method.  The return value can also be
handy to distinguish between supported and unsupported device parameters
in run time.

Greg Kroah-Hartman b98cb4b7fe driver core: remove DEVICE_ID_SIZE define
There is no such thing as a "device id size" in the driver core, so
remove the define and fix up any users of this odd define in the rest of
the kernel.

Alex Dubov ead7077360 memstick: automatically retrieve "INT" value from command response
MemoryStick storage cards, when in parallel mode, send several meaningful bits
of their "INT" register as part of command response.  This data is stored by
host and can be used to spare invocation of "GET_INT" TPC on each data page
transferred between host and card.

for the possibility that memstick layer may need to cycle card's power to get
it out from some unhealthy states.
