From 73da4268fdbae972f617946d1c690f2136964802 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 7 Jan 2017 09:30:08 +0300 Subject: 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.
