Subject: sd-device: use (void) before set_iterate calls
X-Git-Tag: v231~602^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bccfe92e4600632c6ef65ae8eda6ac7782a6aebf;p=platform%2Fupstream%2Fsystemd.git

sd-device: use (void) before set_iterate calls

set_iterate sets the output argument to NULL on error, and the return
value is not used in this case.

CID #1306804-09.
