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 Johan Hovold (2): tty/serdev: add serdev registration interface serial: enable serdev support drivers/tty/serdev/serdev-ttyport.c | 6 ++- drivers/tty/serial/serial_core.c | 4 +- drivers/tty/tty_port.c | 75 +++++++++++++++++++++++++++++++++++++ include/linux/serdev.h | 7 +++- include/linux/tty.h | 9 +++++ 5 files changed, 95 insertions(+), 6 deletions(-) -- 2.13.0
