Sorry for the ping, I worry this patch was missed, because its my first 
contribution and I've sent patch without subscription and it was delayed.


Yeah, the setup is a bit unfortunate. You can sometimes check in the
archives if it made it through:
https://lists.libvirt.org/archives/list/[email protected]/
But there have also been situations when just the archives were broken.

Add missing return value checks to fix the following issues reported
by the static analyzer:

- vah_add_file() call when adding render node path to the AppArmor
  profile (line 1029) was not checked, while there are examples with
  return code check throughout the code.

- vah_add_file() call when adding default render node path (line 1037)
  had the same issue.

- virDriverLoadModule() call when loading the storage driver (line 908)
  was not checked, while there are examples with return code check
  throughout the code.
