From: Johan Hovold johan@kernel.org Date: Fri, 17 Jan 2020 10:50:25 +0100 Subject: [PATCH] USB: serial: keyspan: handle unbound ports
Check for NULL port data in the control URB completion handlers to avoid dereferencing a NULL pointer in the unlikely case where a port device isn't bound to a driver (e.g. after an allocation failure on port probe()).
Fixes: 0ca1268e109a ("USB Serial Keyspan: add support for USA-49WG & USA-28XG") Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Cc: stable stable@vger.kernel.org Reviewed-by: Greg Kroah-Hartman gregkh@linuxfoundation.org Signed-off-by: Johan Hovold johan@kernel.org
Grabbing the prerequisite for the other USB patch also resolved the conflict here, now queued for 4.9 and 4.4.
Thanks for this and the other fixups you're doing here, much appreciated.
