[PATCH 4.19 356/639] vfio/mdev: Follow correct remove sequence

From: Greg Kroah-Hartman
Date: Fri Jan 24 2020 - 06:20:06 EST


From: Parav Pandit <parav@xxxxxxxxxxxx>

[ Upstream commit a6d6f4f160f76d840e59affe664b8d3159e23056 ]

mdev_remove_sysfs_files() should follow exact mirror sequence of a
create, similar to what is followed in error unwinding path of
mdev_create_sysfs_files().

Fixes: 6a62c1dfb5c7 ("vfio/mdev: Re-order sysfs attribute creation")
