It was probably added because of a tool that warned of the unused

Ciao, Marcus
So what about action = NULL instead?
A checker tool should be instructed to ignore that kind of a warning
instead. There are many legitimate cases when a function doesn't use
all of its parameters, in that cases there is no need to take any
special action to silence a warning IMHO.
There is also __attribute__((unused_parameter)) but it's gcc specific.
