Subject: [PATCH v3 0/1] PCI/ERR: fix regression introduced by 6d2c89441571 ("PCI/ERR: Update error status after reset_link()")
- Changes since v2:
* set status to PCI_ERS_RESULT_RECOVERED, in case of successful link
reset, if and only if the initial value of error status is
PCI_ERS_RESULT_DISCONNECT or PCI_ERS_RESULT_NO_AER_DRIVER.
- Changes since v1:
* changed the commit message to clarify what broke post commit 6d2c89441571
* dropped the misnomer post_reset_status variable in favour of a more natural
approach that relies on a boolean to keep track of the outcome of reset_link()
After commit 6d2c89441571 ("PCI/ERR: Update error status after reset_link()")
pcie_do_recovery() no longer calls ->slot_reset() in the case of a successful
reset which breaks error recovery by breaking driver (re)initialisation.
