This is a stupid example of how the compat_version can be implemented.
It's just for illustration and should not be used except for testing.
While there is nothing remarkable to say about the DEVICE_COMPAT_*
variables, note that the placement of the ucidef_set_compat_version
variable is suboptimal in the example and might actually be done in
a separate file or function.
This also gives rise to interesting possibilities:
If ath79 hadn't been introduced already, we could e.g. set
ucidef_set_compat_version 1.1
in a default case for ath79, so all ar71xx devices would be required
to upgrade without keeping settings...
