X-Git-Tag: v2.6.29-rc1~555^2~11
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=06499fac65a273f1de0154679ab04f29dead2bba;p=linux-2.6-omap-h63xx.git

[SCSI] zfcp: fix compile warning

Get rid of this one:

drivers/s390/scsi/zfcp_erp.c: In function 'zfcp_erp_thread':
drivers/s390/scsi/zfcp_erp.c:1400: warning: ignoring return value of
'down_interruptible', declared with attribute warn_unused_result

zfcp_erp_thread is a kernel thread which can't receive any signals.
So introduce a dummy variable and get rid of the warning.
