Subject: fixed DISPLAYUPDATE()
X-Git-Tag: upstream/1.9.3~8^2~39^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=133a50b780be302e726da772592e505d5b143f44;p=platform%2Fupstream%2Flz4.git

fixed DISPLAYUPDATE()

wrong comparison, which was always overflowing (hence was always true)
except when it was not (i386, reported by pmc)
in which case it would never show any information.
