The TMP75B has a different control register, supports 12-bit
resolution and the default conversion rate is 37 Hz.

This patch is corrupted (line wraps as far as I can see). Also, please
version your patches, and add a version log, as described in
Documentation/process/submitting-patches.rst.

Also, please run checkpatch and fix the problems it reports.
That includes the line wraps, but there is also a bad assignment.

Thanks,
Guenter
