That doesn't look right...  I would expect _BIAS_R_SHIFT to shift a
value into the register masked off by _BIAS_R_MASK and therefore that
the above is saying that the definition of one of those two macros is
wrong.  I would not expect something called _BIAS_VOLT_SHIFT here.

What's going on here?

This looks like a reasonable but unrelated fix and should be in a
separate patch.
