From f288cf416ec22de3c5bc18148b6f7620aa32409b Mon Sep 17 00:00:00 2001 From: Devendra Naga Date: Mon, 17 Dec 2012 16:02:41 -0800 Subject: [PATCH] rtc: rtc-davinci: use devm_kzalloc() Use devm_kzalloc() and remove the error path free and the unload free as devm functions take care of freeing resources.
