6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Paul E. McKenney paulmck@kernel.org
commit f2655ac2c06a15558e51ed6529de280e1553c86e upstream.
The current "nretries > 1 || nretries >= max_retries" check in cs_watchdog_read() will always evaluate to true, and thus pr_warn(), if nretries is greater than 1. The intent is instead to never warn on the first try, but otherwise warn if the successful retry was the last retry.
Therefore, change that "||" to "&&".
