Subject: [PATCH AUTOSEL 6.18-6.12] crypto: atmel-sha204a - remove sysfs group before hwrng
Date: Mon, 31 Aug 2026 09:29:04 -0400	[thread overview]
Message-ID: <20260831133314.4125787-516-sashal@kernel.org> (raw)
In-Reply-To: <20260831133314.4125787-1-sashal@kernel.org>

From: Thorsten Blum <thorsten.blum@linux.dev>

[ Upstream commit d58b4a09d7f06750a706b70d068f5a678dad8233 ]

atmel_sha204a_probe() registers the hwrng before creating the sysfs
group. Mirror this order in atmel_sha204a_remove() by removing the sysfs
group before unregistering the hwrng.

LLM Generated explanations, may be completely bogus:

The background searches finished. The Herbert crypto tree is reachable,
and the upstream commit is **`d58b4a09d7f06`** (`crypto: atmel-sha204a -
remove sysfs group before hwrng`). It isn’t in the current **6.18.44**
ancestry — the buggy teardown order is still present in
`drivers/crypto/atmel-sha204a.c`.

That doesn’t change the earlier verdict: **YES** for backport to this
tree. It’s a one-line reorder that should keep the existing `kfree()`
(the LKML version also dropped it, which would be wrong here).
