Subject: [PATCH] hwmon: (pmbus/lm25066) Swap low/high current coefficients for LM5066(i)
The _L low-current mode coefficient values should reference the
datasheet rows with CL=VDD but it seems were mistakenly pulled from
the rows with CL=GND.
This causes the current/power to be reported as approximately double
the actual value when CL=GND and half the actual value when CL=VDD.
