Subject: gpio: fix wrong checking condition for gpio range
From: Haojian Zhuang <[email protected]>
commit ad4e1a7caf937ad395ced585ca85a7d14395dc80 upstream.
If index++ calculates from 0, the checking condition of "while
(index++)" fails & it doesn't check any more. It doesn't follow
the loop that used at here.
Replace it by endless loop at here. Then it keeps parsing
"gpio-ranges" property until it ends.
