I'm looking at this again and think enabling/disabling error reporting for
ports is the responsibility of the port driver, not the AER service.
The following should do the same as this patch, but without making AER
driver handle non-root ports. The report enabling/disabling functions
are already stubbed for '!CONFIG_PCIE_AER' and have checks for aer_cap
and firmware first.
A real patch for this could even make this remove all the aer specific
error report enabling, so it'd be a net-loss in code lines. :)
