-Subject: [PATCH 52/69] PM / OPP: Update the voltage tolerance when adjusting
- the OPP
-
-When the voltage is adjusted, the voltage tolerance is not updated.
-This can lead to situations where the voltage min value is greater
-than the voltage max value. The final result is triggering a BUG()
-in the regulator core.
-Fix this by updating the voltage tolerance values too.
