Suppose this was actually built as a module. How do you pass the
module parameters to this module? Only ways I know of are
./insmod booke_wdt booke_wdt_enabled=1 booke_wdt_period=3
or pass booke_wdt.booke_wdt_enabled=1 on the kernel boot params list.
So the alias is necessary to refer to this module to pass params.
About separate patch, I think it is only with conversion to
module_param() that we need this alias.
Am I missing something?
