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.

* ps3_sys_manager - PS3 system manager driver.
|
|
*
|
|
* The system manager provides an asynchronous system event notification
|
|
* mechanism for reporting events like thermal alert and button presses to
|
|
* guests. It also provides support to control system shutdown and startup.
|
|
*
|
|
* The actual system manager is implemented as an application running in the
|
|
* system policy module in lpar_1. Guests communicate with the system manager
|
|
* through port 2 of the vuart using a simple packet message protocol.
|
|
* Messages are comprised of a fixed field header followed by a message
|
|
* specific payload.
