Merge tag 'driver-core-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core update from Greg KH: "Here is the "big" driver core update for 4.14-rc1. It's really not all that big, the largest thing here being some firmware tests to help ensure that that crazy api is working properly. There's also a new uevent for when a driver is bound or unbound from a device, fixing a hole in the driver model that's been there since the very beginning. Many thanks to Dmitry for being persistent and pointing out how wrong I was about this all along :) Patches for the new uevents are already in the systemd tree, if people want to play around with them. Otherwise just a number of other small api changes and updates here, nothing major. All of these patches have been in linux-next for a while with no reported issues" * tag 'driver-core-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (28 commits) driver core: bus: Fix a potential double free Do not disable driver and bus shutdown hook when class shutdown hook is set. base: topology: constify attribute_group structures. base: Convert to using %pOF instead of full_name kernfs: Clarify lockdep name for kn->count fbdev: uvesafb: remove DRIVER_ATTR() usage xen: xen-pciback: remove DRIVER_ATTR() usage driver core: Document struct device:dma_ops mod_devicetable: Remove excess description from structured comment test_firmware: add batched firmware tests firmware: enable a debug print for batched requests firmware: define pr_fmt firmware: send -EINTR on signal abort on fallback mechanism test_firmware: add test case for SIGCHLD on sync fallback initcall_debug: add deferred probe times Input: axp20x-pek - switch to using devm_device_add_group() Input: synaptics_rmi4 - use devm_device_add_group() for attributes in F01 Input: gpio_keys - use devm_device_add_group() for attributes driver core: add devm_device_add_group() and friends driver core: add device_{add|remove}_group() helpers ...
