/* For the sake of interface compatibility between mini and powerpc code,
|
|
you should try to commit any enhancements you make back upstream so
|
|
that they can be assigned a standard request number. Otherwise, if
|
|
you are creating a new device, you MUST assign it a device ID >= 0x80.
|
|
|
|
Likewise, if you add functionality to any of the existing drivers,
|
|
your must assign it to a request ID >= 0x8000. This will prevent
|
|
problems if a mismatch between ARM and PPC code occurs. Similarly,
|
|
if you add functions, you should always add them to the end, to
|
|
prevent someone from calling the wrong function.
|
|
|
|
Even still, you are encouraged to add in sanity checks and version
|
|
checking to prevent strange bugs or even data loss. --bushing */
