Subject: driver: (adm1275) set the m,b and R coefficients correctly for power
From: Shikhar Dogra <shidogra@xxxxxxxxx>
[ Upstream commit 6faecba0b3da7b617bf72bef422bf0d3bb6dfe7d ]
Seems like coefficient values for m, b and R under power have been
put in the wrong order. Rearranging them properly to get correct
values of coefficients for power.
For specs, please refer to table 7 (page 35) on
http://www.analog.com/media/en/technical-documentation/data-sheets/ADM1075.pdf
