Subject: [PATCH 1/4] regulator: wm831x-dcdc: Fix the logic to choose best
current limit setting
Current code in wm831x_buckv_set_current_limit actually set the current limit
setting greater than specified range.
Fix the logic in wm831x_buckv_set_current_limit to choose the
smallest current limit setting falls within the specified range.
