Subject: [RFC v2 13/16] bus/fslmc: move unplug for some device out of VFIO
Date: Thu, 17 Sep 2026 09:49:13 +0200	[thread overview]
Message-ID: <20260917074917.595603-14-david.marchand@redhat.com> (raw)
In-Reply-To: <20260917074917.595603-1-david.marchand@redhat.com>

Move device unplug out of the code dealing with VFIO, interrupts and
IO devices.

Signed-off-by: David Marchand <david.marchand@redhat.com>

Changes since RFC v1:
- simplified the loop over devices since only devices for ethdev, dma or
  crypto are in the bus device list,
