Subject: mm/damon/sysfs: remove duplicated commit input validity check
Date: Sun, 5 Jul 2026 08:55:54 -0700
DAMON sysfs interface does parameters validation-purpose
damon_commit_ctx() calls for parameters update. Now the same logic is
embedded inside damon_commit_ctx() itself. Hence, the validation in DAMON
sysfs interface is just an unnecessary duplicate. Remove it.
