This series mainly implements the conversions of pci-bridge devices
i82801b11, io3130_upstream/downstream and so on to realize(). Naturally
part of error messages need to be converted to Error, then propagate
to its callers via the argument errp, bonus clean related minor flaw
up. In short, the former patches are prerequisites for latter ones.
v4:
* patch4: changed from patch 5 in v3. use a elegant way to check
the error, like
function(...);
if (function succeeded) {
/* non-error code path here */
foo = bar;
}
or
function(...);
if (function succeeded) {
/* non-error code path here */
foo = bar;
} else {
/* error path here */
return ret;
}
for readability, instead of this:
function(...)
if (function failed) {
return ...; /* or: "goto out" */
}
/* non-error code path here */
foo = bar; [Eduardo Habkost]
meanwhile, split previous patch4 out. [Michael S. Tsirkin]
* patch5: a new patch that replace pci_add_capability() with
pci_add_capability2(). [Eduardo Habkost]
v3:
* patch2: explain the specified means of the return value, also
improve the commit message. [Marcel Apfelbaum]
* patch3: simplify the subject and commit message, fix another
wrong assert. [Marcel Apfelbaum]
* patch4: adjust the subject.
* patch5: fix a wrong optimization for errp. [Eduardo Habkost]
* patch7: a new patch that converts shpc_init() to Error in order
to propagate the error better.
v2:
* patch1: subject and commit message was rewrited by markus.
* patch2: comment was added to pci_add_capability2().
* patch3: a new patch that fix the wrong return value judgment condition.
* patch4: a new patch that fix code style problems.
* patch5: add an errp argument for pci_add_capability to pass
error for its callers.
* patch6: convert part of pci-bridge device to realize.
v1:
* patch1: fix unreasonable return value check
