Subject: [PATCH 0/4] USB: usblcd: disconnect fix and locking clean ups
Date: Thu, 26 Sep 2019 11:12:19 +0200 [thread overview]
Message-ID: <20190926091228.24634-1-johan@kernel.org> (raw)
This series fixes a failure to stop I/O on disconnect() in the usblcd
driver. Turns out there was a lot of legacy cruft in this driver which
could simply be removed.
The first patch is marked for stable and could go into v5.4 while the
rest is v5.5 material. Posting all at once for completeness.
I was tempted to rip out the custom ioctls() used to retrieve the driver
version and bcdDevice (sic!), but decided to leave them in. I doubt
anyone would miss them though so perhaps we should give it a go?
Tested using a mockup device.
