Subject: [PATCH v2 0/2] serdev: fix broken lifetime assumptions
Date: Thu, 18 May 2017 17:32:59 +0200	[thread overview]
Message-ID: <20170518153301.28885-1-johan@kernel.org> (raw)

This series fixes a number of issues with the new serdev code, which was
based on incorrect tty-port lifetime assumptions.

The first patch in v1 of this series disables serdev support by reverting the
patch which hooked into the tty layer in a broken way that leads to crashes and
leaks when deregistering devices. That one has now been applied to tty-linus
with a stable tag (for v4.11).

The remaining two patches again re-enables serdev (first enabled in 4.11, but
soon reverted in stable) for a subset of tty drivers by adding adding a new
interface for registering serdev devices and using that in serial core only.

More details can be found in the individual commit messages.

Johan


Changes in v2
 - rebase on tty-linus
 - drop first two patches that have already been applied
 - remove a stray newline in patch 1/2
 - add Rob's reviewed-by tag
