Merge tag 'driver-core-4.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH: "Here are a small number of debugfs, ISA, and one driver core fix for 4.7-rc4. All of these resolve reported issues. The ISA ones have spent the least amount of time in linux-next, sorry about that, I didn't realize they were regressions that needed to get in now (thanks to Thorsten for the prodding!) but they do all pass the 0-day bot tests. The others have been in linux-next for a while now. Full details about them are in the shortlog below" * tag 'driver-core-4.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: isa: Dummy isa_register_driver should return error code isa: Call isa_bus_init before dependent ISA bus drivers register watchdog: ebc-c384_wdt: Allow build for X86_64 iio: stx104: Allow build for X86_64 gpio: Allow PC/104 devices on X86_64 isa: Allow ISA-style drivers on modern systems base: make module_create_drivers_dir race-free debugfs: open_proxy_open(): avoid double fops release debugfs: full_proxy_open(): free proxy on ->open() failure kernel/kcov: unproxify debugfs file's fops
