USB controller ASM1042 stops working after commit de3ef1eb1cd0 ("PM / core: Drop run_wake flag from struct dev_pm_info").
The device in question is not power managed by platform firmware, furthermore, it only supports PME# from D3cold: Capabilities: [78] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0-,D1-,D2-,D3hot-,D3cold+) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME-
Before commit de3ef1eb1cd0, the device never gets runtime suspended. After that commit, the device gets runtime suspended, so it does not respond to any PME#.
Apologies for my lack of PM expertise. I don't think the device would *respond* to PME#, would it? I would think the device would potentially *generate* a PME#.
Do you want me to send another version with updated commit message?
Yes, please.
I can also split it to two commits if you desire.
No, that's not necessary.
Thanks, Rafael
