Subject: vfio-mdev: remove some dead code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=73da4268fdbae972f617946d1c690f2136964802;p=linux-beck.git

vfio-mdev: remove some dead code

We set info.count to 1 in mtty_get_irq_info() so static checkers
complain that, "Why do we have impossible conditions?"  The answer is
that it seems to be left over dead code that can be safely removed.
