Hi Guenter,

LM95235 is register compatible to LM95245.

Also update link to LM95245 data sheet, and drop the link to the
datasheet from the driver source to simplify code maintenance.

v2: Drop link to datasheet from driver source.
     Drop DEVNAME.
     Update MODULE_DESCRIPTION.
     Use the same driver_data values for supported chips
     since the field is not used by the driver.

Missing space before opening parenthesis, checkpatch complains about
it. Your original patch had it right, not sure what happened?

Me not either. The other patch has the same problem. Fixed up both.

Everything else looks OK, so:
