[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. Signed-off-by: Frank Pavlic <fpavlic@de.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
