[Qemu-devel] [PATCH 05/31] vfio: Clean up error reporting after previous commit

2018-10-08 Thread Markus Armbruster
The previous commit changed vfio's warning messages from

vfio warning: DEV-NAME: Could not frobnicate

to

warning: vfio DEV-NAME: Could not frobnicate

To match this change, change error messages from

vfio error: DEV-NAME: On fire

to

vfio DEV-NAME: On fire

Note the loss of "error".  If we think marking error messages that way
is a good idea, we should mark *all* error messages, i.e. make
error_report() print it.
