From 72dca06f62c50415de3202f204200f58769d0b8b Mon Sep 17 00:00:00 2001 From: Aniroop Mathur Date: Sun, 28 Dec 2014 22:08:38 +0530 Subject: [PATCH] regulator: core: Avoid negative regulator no & initialize it to -1 This patch initializes regulator_no to -1 to avoid extra subtraction operation performed every time we register a regulator and avoid negative regulator no in its name.
