Date: Thu, 2 May 2019 12:22:24 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: "Tobin C. Harding" <me@...in.cc> Cc: "Rafael J. Wysocki" <rafael@...nel.org>, cl@...ux.com, tycho@...ho.ws, willy@...radead.org, linux-kernel@...r.kernel.org Subject: [PATCH] kobject: clean up the kobject add documentation a bit more Commit 1fd7c3b438a2 ("kobject: Improve doc clarity kobject_init_and_add()") tried to provide more clarity, but the reference to kobject_del() was incorrect. Fix that up by removing that line, and hopefully be more explicit as to exactly what needs to happen here once you register a kobject with the kobject core. Cc: Tobin C.
