(i) pressure is 20-bit unsigned, not signed; the buffer description is incorrect; for raw reads, this is just cosmetic (ii) temperature is 12-bit signed, not 16-bit; this affects readout of temperatures below zero as the sign bit is incorrectly processed reported via private mail Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Reported-by: Robert Deliën <robert@delien.nl> Signed-off-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> 
commit d29f592929489d0a7c414396fae28119f3d280e1 upstream.

(i) pressure is 20-bit unsigned, not signed; the buffer description
is incorrect; for raw reads, this is just cosmetic

(ii) temperature is 12-bit signed, not 16-bit; this affects
readout of temperatures below zero as the sign bit is incorrectly
processed
