If anyone has any objections, please let me know. ------------------ From: Linus Walleij commit 906402a44b5d090e9c330c562b8aa65c80790ccc upstream. This fixes up the handling of fixed regulator polarity inversion flags: while I remembered to fix it for the undocumented "reg-fixed-voltage" I forgot about the official "regulator-fixed" binding, there are two ways to do a fixed regulator. The error was noticed and fixed.
