[PATCH net 0/3] s390/net: Cleanup some code checker findings

[Alexandra Winter <wintera@linux.ibm.com>]

clean up smatch findings in legacy code. I was not able to provoke
any real failures on my systems, but other hardware reactions,
timing conditions or compiler output, may cause failures.

There are still 2 smatch warnings left in s390/net:

drivers/s390/net/ctcm_main.c:1326 add_channel() warn: missing error code 'rc'
This one is a false positive.

drivers/s390/net/netiucv.c:1355 netiucv_check_user() warn: argument 3 to %02x specifier has type 'char'
Postponing this one, need to better understand string handling in iucv.

There are several sparse warnings left in ctcm, like:
drivers/s390/net/ctcm_fsms.c:573:9: warning: context imbalance in 'ctcm_chx_setmode' - different lock contexts for basic block
Those are mentioned in the source, no plan to rework.

Alexandra Winter (3):
  s390/ctcm: fix variable dereferenced before check
  s390/ctcm: fix potential memory leak
  s390/lcs: fix variable dereferenced before check
