Merge tag 'driver-core-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core update from Greg KH: "Here's the driver core patches for 3.18-rc1. Just a few small things, and the addition of a new interface to dump firmware "core dumps" to userspace through sysfs that the wireless and graphic drivers want to use. All of these have been in linux-next for a while" * tag 'driver-core-3.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: dynamic_debug: change __dynamic_<foo>_dbg return types to void driver/base/node: remove unnecessary kfree of node struct from unregister_one_node devres: Improve devm_kasprintf()/kvasprintf() support Documentation: devres: Add missing devm_kstrdup() managed interface Documentation: devres: Add missing IRQ functions firmware_class: make sure fw requests contain a name driver core: Remove kerneldoc from local function attribute_container: fix coding style issues attribute_container: fix whitespace errors drivers/base: Fix length checks in create_syslog_header()/dev_vprintk_emit() device coredump: add new device coredump class Documentation/sysfs-rules.txt: Add device attribute error code documentation
