[PATCH] regulator: wm8350: correct the max_uV of LDO

From: Laxman Dewangan
Date: Thu Sep 19 2013 - 08:18:53 EST


As per datasheet, voltage range for LDOs are as follows:

0000 = 0.9V
...(50mV steps)
01111 = 1.65V
10000 = 1.8V
... (100mV stepns)
11111 = 3.3V

So, there is no selector for 1.65V to 1.8V.
Correcting the range for max_uV for selector between 0 to 15.

When trying to understand the usage of linear_range, found the above issue
in code. I do not have hardware to validate but though that let's send this
for review. Probably this is real bug.
