+Subject: [PATCH 17/19] fix: random: remove unused tracepoints (v5.18)
+
+See upstream commit :
+
+  commit 14c174633f349cb41ea90c2c0aaddac157012f74
+  Author: Jason A. Donenfeld <Jason@zx2c4.com>
+  Date:   Thu Feb 10 16:40:44 2022 +0100
+
+    random: remove unused tracepoints
+
+    These explicit tracepoints aren't really used and show sign of aging.
+    It's work to keep these up to date, and before I attempted to keep them
+    up to date, they weren't up to date, which indicates that they're not
+    really used. These days there are better ways of introspecting anyway.
