Subject: eina: fix clang compilation with EINA_FALLTHROUGH
X-Git-Tag: upstream/1.20.0~753
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=81bcc14615b7437f1548cee415347bdfb22bbede;p=platform%2Fupstream%2Fefl.git

eina: fix clang compilation with EINA_FALLTHROUGH

btw, using clang 4.0.0, I can't produce fallthrough warnings using
-Weverything, -Wall or -Wimplicit-fallthrough
