[PATCH 00/20] qdev/qom: Remove explicit type names from error_setg() calls

[Eduardo Habkost]

One of the obstacles when refactoring the QOM property parsing
code are the references to the object itself in the error code,
to generate "Property '<TYPE>.<PROP>' can't take value ..." error
messages.  This makes it hard to isolate the string parsing code
into functions that are independent from QOM.

The simple solution for that would be to just remove the prefix
and have less descriptive error messages.

A slightly better solution is to make the code that parses
-device and -object add a
  "Property '<TYPE>.<PROP>' can't take value '<VALUE>': "
prefix automatically when encountering an error
when setting a property.  This is the approach implemented in
this series.

Eduardo Habkost (20):
  qom: Add prefix to error message inside object_property_parse()
  qdev: Stop using error_set_from_qdev_prop_error() for netdev property
  qdev: Stop using error_set_from_qdev_prop_error() for audiodev
    property
  qdev: Stop using error_set_from_qdev_prop_error() for mac property
  qdev: Stop using error_set_from_qdev_prop_error() for devfn property
  qdev: Stop using error_set_from_qdev_prop_error() for PCI host device
    property
  qdev: Stop using error_set_from_qdev_prop_error() for css devno
    property
  qdev: Delete unused error_set_from_qdev_prop_error() function
