Subject: [PATCH 0/4] ser_gigaset: fic deallocation of platform device structure

Sascha Levin reported that the syzkaller fuzzer triggered a WARNING in
ser_gigaset (see https://lkml.kernel.org/g/56587467.8050102@oracle.com ). It
turned out that ser_gigaset has always deallocated its platform device
structure incorrectly. Tilman submitted the patch that fixes that (3/4) and a
related cleanup (4/4).

Tilman also submitted a minor cleanup of some NULL checks (1/4) that prompted
Alan to turn those checks into WARN_ONs (2/4). If no one hits these WARN_ONs in
the next couple of releases these WARN_ONs should be removed.

Alan Cox (1):
  ser_gigaset: turn nonsense checks into WARN_ON

Tilman Schmidt (3):
  ser_gigaset: fix up NULL checks
  ser_gigaset: fix deallocation of platform device structure
  ser_gigaset: remove unnecessary kfree() calls from release method
