From 55827f4aa6442ddd1d6a4e1e32f2f457eb113c22 Mon Sep 17 00:00:00 2001 From: Doug Anderson Date: Fri, 15 Feb 2013 13:18:35 +0000 Subject: i2c: Remove unneeded xxx_set_drvdata(..., NULL) calls There is simply no reason to be manually setting the private driver data to NULL in the remove/fail to probe cases. This is just extra cruft code that can be removed. A few notes: * Nothing relies on drvdata being set to NULL. * The __device_release_driver() function eventually calls dev_set_drvdata(dev, NULL) anyway, so there's no need to do it twice. * I verified that there were no cases where xxx_get_drvdata() was being called in these drivers and checking for / relying on the NULL return value. This could be cleaned up kernel-wide but for now just take the baby step and remove from the i2c subsystem.
