From 4eded6d14f5b7bb857b68872970a40cf3105c015 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 3 Sep 2024 07:33:40 +0800 Subject: crypto: testmgr - Hide ENOENT errors When a crypto algorithm with a higher priority is registered, it kills the spawns of all lower-priority algorithms. Thus it is to be expected for an algorithm to go away at any time, even during a self-test. This is now much more common with asynchronous testing. Remove the printk when an ENOENT is encountered during a self-test. This is not really an error since the algorithm being tested is no longer there (i.e., it didn't fail the test which is what we care about).
