Hi Greg,

This patch causes a deadlock, the thermal framework stops. Please check this fix (I found it before posting exactly the same solution): https://lkml.org/lkml/2019/11/12/1075

Sorry about that.

I have verified it on OdroidXU4 and it works. It needs some cleaning in the commit message, though. I have added to CC the author: Wei Wang

I don't know in how many stable trees it was applied, but should be fix there also.

I checked my mailbox and it seems it was backported to: 4.4, 4.9, 4.14, 4.19, 5.2 (EOL) and 5.3

Thanks
