Subject: test-xi2: add an extra NULL-check
X-Git-Url: https://diplodocus.org/git/xorg-xinput/commitdiff_plain/5a8f3121c7f64dbb47fad99c027389e7d78453e4?ds=inline;hp=3ea8f02027b18cf06774c8f26a719e321e9a78f2

test-xi2: add an extra NULL-check

Shuts up coverity because it doesn't know that by the time we get here, we're
guaranteed that the device exists. Otherwise the list() call a few lines above
would've failed and we wouldn't get here.
