Subject: [PATCH 0/2][next] vfio/ccw: Replace one-element array with
 flexible-array member

Hi!

This small series aims to replace a one-element array with a
flexible-array member in struct vfio_ccw_parent.

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE
routines on memcpy() and help us make progress towards globally
enabling -fstrict-flex-arrays=3 [1].
