[PATCH v4 0/1] PCI/ERR: fix regression introduced by 6d2c89441571 ("PCI/ERR: Update error status after reset_link()")

[Hedi Berriche]

This is essentially a resend of v3 as it failed to get enough traction;
no code change, I only added Sinan Kaya's Reviewed-by.

- Changes since v3:
* added Sinan Kaya <okaya@xxxxxxxxxx> Reviewed-by

- 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.
