[Qemu-devel] [PULL 5/6] hw/usb/dev-mtp: Guard inotify usage with CONFIG_INOTIFY1

[Gerd Hoffmann <kraxel@redhat.com>]

From: Matthew Fortune <Matthew.Fortune@imgtec.com>

inotify_init1 usage was guarded by a check for linux but does not
exist on older distributions like CentOS 5 resulting in build
failures.
