Value in chip->vendor.duration[TPM_SHORT] is in jiffies not in milliseconds.
(As I know it's not the same. Jiffy is in range 1-10 ms.)
I know the result may be the same, but it is unclear.

Maybe... value should be compared (to 1000) before conversion?
or...
If after conversion, there should be something like this:
if (chip->vendor.duration[TPM_SHORT] < (HZ/100)) /* less
than 10ms ? */
chip->vendor.duration[TPM_SHORT] = HZ;

What do you think?

Marcin
