From 531bc938f9c54c5c0998ec537195ed4a3c74a608 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Tue, 17 Jun 2014 16:14:56 +0100 Subject: [PATCH] usb: gadget: r8a66597-udc: use devm_kzalloc() to allocate driver state Update driver to use devm_kzalloc() to make tracking of resources easier. Also remove the exit point via cleanup as there's no cleanup necessary from this point now. As a note, also removes the error print as the allocation calls produce errors if they do not return memory.
