Guenter hi,
Yeah - I see your point. But here is the thing - 
UFS devices support only a subset of scsi commands.
It does not support ATA_16 nor SMART attributes.
Moreover, you can't read UFS attributes using any other scsi/ATA/SATA
Commands, nor it obey the ATA temperature sensing conventions.
So unless you want to totally break the newly born drivetemp - 
Better to leave ufs devices out of it.

Another option is to put a ufs module under hwmon.
Do you see why would that be more advantageous to using the thermal core?
Provided that you are not going to deprecate it (Intel's wifi card is still using it)...

As for adding those attributes to ufs-sysfs - 
this is just a supplementary as all other attributes are exposed this way.

Thanks,
Avri
