5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lukas Wunner lukas@wunner.de
commit 6633875250b38b18b8638cf01e695de031c71f02 upstream.
PCIe r6.0 defined five additional errors in the Uncorrectable Error Status, Mask and Severity Registers (PCIe r7.0 sec 7.8.4.2ff).
lspci has been supporting them since commit 144b0911cc0b ("ls-ecaps: extend decode support for more fields for AER CE and UE status"):
https://git.kernel.org/pub/scm/utils/pciutils/pciutils.git/commit/?id=144b09...
Amend the AER driver to recognize them as well, instead of logging them as "Unknown Error Bit".
