It goes beyond that, it that the logs are now going to be way easier
to read with a consistent formatting of verbose messages. I think this
is a good idea, and with a lack of precedent (that I know of) you may
be setting a tree-wide standard here. CC Markus who is into logs and
errors. Patch 2 sums up nicely the proposed format:

               if (DEBUG_IMX_GPIO) { \
-                  fprintf(stderr, "%s: " fmt , __func__, ##args); \
+                  fprintf(stderr, "[%s]%s: " fmt , TYPE_IMX_GPIO, \
+                                                   __func__, ##args); \

which is:

[QOM_TYPE_NAME]reporting_function: some printf type message

so general RFC on what other think of it. Are there any existing
in-tree standards to factor in? I am OK in principle.
