[PATCH 7.3.y 2/2] mm/damon/sysfs-schemes: drop centralized filter range arg validations

[Sasha Levin <sashal@kernel.org>]

From: SJ Park <sj@kernel.org>

[ Upstream commit 1d2397b2c414e3f1fb536666ccc21d4065a3d9a6 ]

DAMON sysfs interface is validating wrong range arguments for DAMOS
filters.  Now the core layer is doing the same validation.  Drop the
duplicated validation in DAMON sysfs interface.
