Some would note these should be on separate lines, but I'll note that
since we have it, these should be:
VIR_AUTOPTR(char *) swtpm_user = NULL;
VIR_AUTOPTR(char *) swtpm_group = NULL;
+ int ret = -1;
+
+ if (virConfGetValueString(conf, "swtpm_user", &swtpm_user) < 0)
+ goto cleanup;
+ if (swtpm_user && virGetUserID(swtpm_user, &cfg->swtpm_user) < 0)
+ goto cleanup;
+
+ if (virConfGetValueString(conf, "swtpm_group", &swtpm_group) < 0)
+ goto cleanup;
+ if (swtpm_group && virGetGroupID(swtpm_group, &cfg->swtpm_group) <
0)
+ goto cleanup;
+
+ ret = 0;
+ cleanup:
+ VIR_FREE(swtpm_user);
+ VIR_FREE(swtpm_group);
Thus freeing you of needing this and perhaps changing your logic above.
I "understand" the "norm" is to just purely copy and then have
another
patch, but I really believe in this case it's so obvious that a separate
patch isn't required especially since VIR_AUTOFREE is more commonly used.
+ return ret;
+}

one more blank line. If you feel you must create two patches out of
this one patch, then go ahead, I trust that you can do that, but I think
we really should use the VIR_AUTOPTR more now...
BTW: I have a feeling VIR_AUTOPTR and 2 empty lines will become a
recurring theme...
