Subject: Re: [PATCH v2] hwmon: Driver for temperature sensors on SATA drives

Guenter,

My working tree is available here:

  https://git.kernel.org/pub/scm/linux/kernel/git/mkp/linux.git/log/?h=5.6/drivetemp

A few notes:

 - Before applying your patch I did s/satatemp/drivetemp/

 - I get a crash in the driver core during probe if the drivetemp module
   is loaded prior to loading ahci or a SCSI HBA driver. This crash is
   unrelated to my changes. Haven't had time to debug.

 - I tweaked your ATA detection heuristics and now use the cached VPD
   page 0x89 instead of fetching one from the device.

 - I also added support for reading the temperature log page on SCSI
   drives.

 - Tested with a mixed bag of about 40 SCSI and SATA drives attached.

 - I still think sensor naming needs work. How and where are the
   "drivetemp-scsi-8-140" names generated?

I'll tinker some more but thought I'd share what I have for now.
