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
