3.16.44-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Marcin Niestroj <[email protected]> commit 1b211d48abaa0e12e6e6177c0316ff55d11fdfce upstream. Datasheet of each device (lps331ap, lps25h, lps001wp, lps22hb) says that the pressure and temperature data is a 2's complement. I'm sending this the slow way, as negative pressures on these are pretty unusual and the nature of the fixing of multiple device introduction patches will make it hard to apply to older kernels - Jonathan.
