Subject: Fix the termination of the readlink result
X-Git-Tag: 1.16.4~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dc1edd140f10b459626d903382df28c74672739b;p=platform%2Fupstream%2Flibinput.git

Fix the termination of the readlink result

nread is the number of bytes put into the buffer, let's terminate it there
instead of one byte over. This only worked because execdir was initialized to
zero.
