From 327531bada36e5786b13bb6918ad8afc545adfa2 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sun, 22 Aug 2010 22:38:15 +0800 Subject: regulator: tps6586x-regulator - fix value range checking for val val is used as array index of ri->voltages. Thus the valid value range should be 0 .. ri->desc.n_voltages - 1.
