[Qemu-trivial] [PATCH RFC 0/5] Another patchset try to clean up around qerror_report_err()

[Qemu-trivial] [PATCH RFC 0/5] Another patchset try to clean up around qerror_report_err()

[zhanghailiang]

Hi,

I have noticed Markus's previous patchset 
"Clean up around error_get_pretty(), qerror_report_err()".

This is another patch series trying to do the same thing.
I'm not sure if he has missed this places or these modifies are false.

So, please review... 

Thanks.

[Qemu-trivial] [PATCH RFC 1/5] serial-pci: Avoid qerror_report_err() outside QMP command handlers

[zhanghailiang]

qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP.  It should not be used
elsewhere.  Replace by error_report_err() in serial_pci_init() and
multi_serial_pci_init().

This breaks the error reply when you hot plug the devices via QMP
device_add.

The correct solution is my "[PATCH 06/10] serial-pci: Convert to
realize".

This breaks QMP device_add's error reply.

The patches I posted together remove all calls of qdev_init().  Once
they're all merged, the function should be simply dropped.

Hard to see, but this is actually dead code.

[PATCH v2 0/2] pci: Bury dead legacy commands pci_add, pci_del

[Qemu-trivial] [PATCH RFC 4/5] pci-assign: Avoid qerror_report_err() outside QMP command handlers

[zhanghailiang]

qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP.  It should not be used
elsewhere.  Replace by error_report_err() in assigned_initfn().

This breaks the error reply when you hot plug the devices via QMP
device_add.

A correct solution is my "[PATCH 10/10] pci-assign: Convert to realize".

This one's good.  My commit 565f65d "error: Use error_report_err() where
appropriate" cleaned up this pattern, but a few more instances have
since crept in, and this is one.

I can see another one in hw/arm/virt.c machvirt_init().

Help with qerror elimination is of course appreciated!  However, there's
overlap with related patches in flight.  Easy to miss, because there are
so many of them.  I'll elaborate in replies to your patches.
