Subject: [PATCH v7 14/17] PCI/AER: Rename struct aer_stats to aer_info
From: Karolina Stolarek <karolina.stolarek@...cle.com>
Update name to reflect the broader definition of structs/variables that are
stored (e.g. ratelimits). This is a preparatory patch for adding rate limit
support.
[bhelgaas: "aer_report" -> "aer_info"]
