drivers: base: remove check for callback in coredump_store() (2018-03-23 18:08:02 +0100)

Driver core patches for 4.17-rc1

Here is the "big" set of driver core patches for 4.17-rc1.

There's really not much here, just a bunch of firmware code refactoring
from Luis as he attempts to wrangle that codebase into something that is
managable, along with a bunch of userspace tests for it. Other than
that, a handful of small bugfixes and reverts of things that didn't work

Full details are in the shortlog, it's not all that much.

All of these have been in linux-next for a while with no reported

Andy Shevchenko (1):
lib/kobject: Join string literals back

Arvind Yadav (4):
base: soc: use put_device() instead of kfree()
driver core: platform: use put_device() if device_register fail
driver core: node: use put_device() if device_register fail
driver core: cpu: use put_device() if device_register fail

rename: _request_firmware_load() fw_load_sysfs_fallback()
firmware: fix checking for return values for fw_add_devm_name()
firmware: add helper to check to see if fw cache is setup
test_firmware: modify custom fallback tests to use unique files
firmware: ensure the firmware cache is not used on incompatible calls
firmware: fix typo on pr_info_once() when ignore_sysfs_fallback is used
firmware: add firmware_request_cache() to help with cache on reboot
mt7601u: use firmware_request_cache() to address cache on reboot

Stephen Rothwell (1):
firmware: explicitly include vmalloc.h
