Subject: mtd locking fix and cleanups
Date: Mon, 23 Aug 2021 09:33:51 +0200 [thread overview]
Message-ID: <20210823073359.705281-1-hch@lst.de> (raw)
Hi mtd maintainers,
the first series in this patch fixes a lock order reversal reported by
Guenter based on a recent commit, although from code inspection it should
have been around for much longer.
The rest is drive-by cleanups in the area that I noticed while trying to
understand the locking changes. These are untested and need to be handled
with care!
