From 4ceb73ae5a09416e040bce8bcfa7218dc5149ad8 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Sun, 24 Feb 2013 19:26:25 -0800 Subject: regulator: db8500-prcmu - remove incorrect __exit markup Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes.
