Subject: [PATCH v8 12/22] counter: Rename counter_count_function to counter_function
The phrase "Counter Count function" is verbose and unintentionally
implies that function is a Count extension. This patch adjusts the
Counter subsystem code to use the more direct "Counter function" phrase
to make the intent of this code clearer. The phrase "Count action" is
adjusted herein as well for the same reason.
