Subject: [PATCH 0/2] regcache: Validate bounds of regcache drop requests
Date: Mon, 26 Oct 2026 23:32:06 +0000 [thread overview]
Message-ID: <20261026-regmap-drop-region-min-max-v1-0-2c28637ede23@kernel.org> (raw)
It is not valid for a caller to try to drop a range of registers from
the cache where the minimum register is greater than the maximum register,
and doing so is likely to trigger bugs in the caches. Reject such
invalid inputs and add a KUnit test for it.
