[PATCH v3] PCI/AER: Do not clear AER bits if we don't own AER

2018-07-30 Thread Alexandru Gagniuc
When we don't own AER, we shouldn't touch the AER error bits. Clearing error bits willy-nilly might cause firmware to miss some errors. In theory, these bits get cleared by FFS, or via ACPI _HPX method. These mechanisms are not subject to the problem. This race is mostly of theoretical significanc
