Subject: selftests/damon/_debugfs_common: hide expected error message from test_write_result()
Date: Mon, 28 Oct 2024 16:30:55 -0700
DAMON debugfs interface selftests use test_write_result() to check if
valid or invalid writes to files of the interface success or fail as
expected. File write error messages from expected failures are only
making the output noisy. Hide such expected error messages.
