From 28ade0f217a3a3ff992b01e06e6e425c250a8406 Mon Sep 17 00:00:00 2001 From: Wolfram Sang <w.sang@pengutronix.de> Date: Fri, 21 May 2010 00:50:17 +0200 Subject: [PATCH] mfd: Remove unneeded and dangerous clearing of clientdata Unlike real i2c-devices which get detached from the driver, dummy-devices get truly unregistered. So, there has never been a need to clear the clientdata because the device will go away anyhow. For the occasions fixed here, clearing clientdata was even dangerous as the structure was freed already.
