From 17a1e4fa3f7f07f541c751745b5aa6f2fcab9a48 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Thu, 5 Aug 2021 22:19:01 -0300 Subject: vfio/samples: Delete useless open/close The core code no longer requires these ops to be defined, so delete these empty functions and leave the op as NULL. mtty's functions only log a pointless message, delete that entirely.
