Alan / Greg,

A small step (hopefully in right direction) to move this driver out of staging, into a right place in mainline.

The patch set has,

* Update TODO to add the requirement to remove global references.
* The 2nd patch addresses the issue by removing the global references.
To achieve this, the platform device being added from the board-XX.c inside arch/XX/ needs to expose a function'st_get_plat_device' which returns a pointer to the platform_device struct.

Now there are 3 contexts in the driver:
1. platform device/driver context - probe/remove, sysfs show/store, and rfkill ops
2. TTY context - tty_open/close/_receive since it is ldisc driver
3. Process context - st_register/_unregister/_write called from the protocol drivers registering to ST upon calling open/close on /dev/radio0, /dev/tigps sort of char devices or hci0 sort of interfaces

In platform device/driver context's dev_set_drvdata/get_drvdata is used. TTY's disc_data in TTY context and for the 3rd context and to combine 1 and 2 - the platform device exposed in board-XX.c will be used.
