[PATCH] s390: minor s390 network driver fixes 

Hi Jeff,
this is a RESEND of the nine s390 network driver patches.
I finally found  that my kmail corrupted almost every patch
I sent the last time. Please apply these 9 patches and forget
about my first attempt! Sorry for the delay, I had some fights
with sendmail, IMAP and mutt configuration.

Frank

[RESEND PATCH 1/9] s390: minor s390 network driver fixes

From: Frank Pavlic <fpavlic@de.ibm.com>
	- iucv driver:
          use do { } while (0) constructs
	  instead of empty defines to avoid compile bugs.
        - ctc driver:
          missing lock initialization added
        - lcs driver:
          BUG_ON usage was removed accidently
	  with the last lcs patch.
          Put them back in place.
