Revert "PCI/ASPM: Refactor L1 PM Substates Control Register programming"
commit ff209ecc376a2ea8dd106a1f594427a5d94b7dd3 upstream.
This reverts commit 5e85eba6f50dc288c22083a7e213152bcc4b8208.
Thomas Witt reported that 5e85eba6f50d ("PCI/ASPM: Refactor L1 PM Substates
Control Register programming") broke suspend/resume on a Tuxedo
Infinitybook S 14 v5, which seems to use a Clevo L140CU Mainboard.
The main symptom is:
iwlwifi 0000:02:00.0: Unable to change power state from D3hot to D0, device inaccessible
nvme 0000:03:00.0: Unable to change power state from D3hot to D0, device inaccessible
and the machine is only partially usable after resume. It can't run dmesg
and can't do a clean reboot. This happens on every suspend/resume cycle.
Revert 5e85eba6f50d until we can figure out the root cause.
