Merge tag 'driver-core-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH: "Here is the big driver core update for 4.13-rc1. The large majority of this is a lot of cleanup of old fields in the driver core structures and their remaining usages in random drivers. All of those fixes have been reviewed by the various subsystem maintainers. There's also some small firmware updates in here, a new kobject uevent api interface that makes userspace interaction easier, and a few other minor things. All of these have been in linux-next for a long while with no reported issues" * tag 'driver-core-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (56 commits) arm: mach-rpc: ecard: fix build error zram: convert remaining CLASS_ATTR() to CLASS_ATTR_RO() driver-core: remove struct bus_type.dev_attrs powerpc: vio_cmo: use dev_groups and not dev_attrs for bus_type powerpc: vio: use dev_groups and not dev_attrs for bus_type USB: usbip: convert to use DRIVER_ATTR_RW s390: drivers: convert to use DRIVER_ATTR_RO/WO platform: thinkpad_acpi: convert to use DRIVER_ATTR_RO/RW pcmcia: ds: convert to use DRIVER_ATTR_RO wireless: ipw2x00: convert to use DRIVER_ATTR_RW net: ehea: convert to use DRIVER_ATTR_RO net: caif: convert to use DRIVER_ATTR_RO TTY: hvc: convert to use DRIVER_ATTR_RW PCI: pci-driver: convert to use DRIVER_ATTR_WO IB: nes: convert to use DRIVER_ATTR_RW HID: hid-core: convert to use DRIVER_ATTR_RO and drv_groups arm: ecard: fix dev_groups patch typo tty: serdev: use dev_groups and not dev_attrs for bus_type sparc: vio: use dev_groups and not dev_attrs for bus_type hid: intel-ish-hid: use dev_groups and not dev_attrs for bus_type ...
