If anyone has any objections, please let me know. ------------------ From: Shikhar Dogra [ 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 Fixes: 904b296f308d ("hwmon: (adm1275) Introduce configuration data structure for coeffcients") Signed-off-by: Shikhar Dogra Signed-off-by: Guenter Roeck Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- drivers/hwmon/pmbus/adm1275.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- a/drivers/hwmon/pmbus/adm1275.c +++ b/drivers/hwmon/pmbus/adm1275.c @@ -101,8 +101,8 @@ static const struct coefficients adm1075 [0] = { 27169, 0, -1 }, /* voltage */ [1] = { 806, 20475, -1 }, /* current, irange25 */ [2] = { 404, 20475, -1 }, /* current, irange50 */ - [3] = { 0, -1, 8549 }, /* power, irange25 */ - [4] = { 0, -1, 4279 }, /* power, irange50 */ + [3] = { 8549, 0, -1 }, /* power, irange25 */ + [4] = { 4279, 0, -1 }, /* power, irange50 */ }; static const struct coefficients adm1275_coefficients[] = {
