[PATCH v2 00/11] VFIO: misc cleanups

[Zhenzhong Duan <zhenzhong.duan@intel.com>]

Hi

This is a cleanup series to change functions in hw/vfio/ to return bool 
when the error is passed through errp parameter, also some cleanup
with g_autofree.

See discussion at https://lists.gnu.org/archive/html/qemu-devel/2024-04/msg04782.html

This series processed below files:
hw/vfio/container.c
hw/vfio/iommufd.c
hw/vfio/cpr.c
backends/iommufd.c

So above files are clean now, there are still other files need processing
in hw/vfio.

Test done on x86 platform:
vfio device hotplug/unplug with different backend
reboot

Thanks
Zhenzhong

- split out g_autofree code as a patch (Cédric)
