Subject: [PATCH 0/2] can: fix USB altsetting bugs
Date: Tue, 10 Dec 2019 12:32:29 +0100 [thread overview]
Message-ID: <20191210113231.3797-1-johan@kernel.org> (raw)
We had quite a few driver using the first alternate setting instead of
the current one when doing descriptor sanity checks. This is mostly an
issue on kernels with panic_on_warn set due to a WARN() in
usb_submit_urn(). Since we've started backporting such fixes (e.g. as
reported by syzbot), I've marked these for stable as well.
The second patch here is a related cleanup to prevent future issues.
