Subject: PCI/AER: Factor out ERR_NONFATAL status bit clearing
X-Git-Tag: v4.19-rc1~123^2~20^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5b6c09660da8779dd545fa717c2b0cc79d477c9e;p=thirdparty%2Fkernel%2Flinux.git

PCI/AER: Factor out ERR_NONFATAL status bit clearing

aer_error_resume() clears all ERR_NONFATAL error status bits.  This is
exactly what pci_cleanup_aer_uncorrect_error_status(), so use that instead
of duplicating the code.
