[PATCH 3/4] random/trace: remove unused trace_extract_entropy_user()

From: Yann Droneaud
Date: Thu May 21 2020 - 10:07:25 EST


Since commit 90ea1c6436d2 ('random: remove the blocking pool')
trace_extract_entropy_user() is unused.

As the result, trace_extract_entropy() is the only trace
function needed, thus there's no need for a separate event
class / event.
