From cb0f7d35e385fc242c76bfe7f1d68c1904c6f965 Mon Sep 17 00:00:00 2001 From: Devendra Naga Date: Mon, 18 Jun 2012 23:14:31 +0530 Subject: pinctrl/pinctrl-tegra: remove IS_ERR checking of pmx->pctl pinctrl_register returns a pointer of struct type struct pinctrl_dev, if successfully registered to pinctrl subsystem, otherwise returns NULL, and there wont' be any pointers which are not dereferencible. They are not type of pointer addresses but are kind of error codes rather actual addresses, but are a kind of return codes of functions returning integer types. return -ENODEV if device registration fails.
