Subject: [PATCH 2/2] regulator: bd71828: Fix .n_voltages settings
Date:   Sun, 23 May 2021 15:10:45 +0800

Current .n_voltages settings do not cover the latest 2 valid selectors,
so it fails to set voltage for the hightest voltage support.
The latest linear range has step_uV = 0, so it does not matter if we
count the .n_voltages to maximum selector + 1 or the first selector of
latest linear range + 1.
To simplify calculating the n_voltages, let's just set the
.n_voltages to maximum selector + 1.
