Merge tag 'driver-core-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg Kroah-Hartman: "Here are some small driver core and firmware fixes for 4.17-rc3 There's a kobject WARN() removal to make syzkaller a lot happier about some "normal" error paths that it keeps hitting, which should reduce the number of false-positives we have been getting recently. There's also some fimware test and documentation fixes, and the coredump() function signature change that needed to happen after -rc1 before drivers started to take advantage of it. All of these have been in linux-next with no reported issues" * tag 'driver-core-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: firmware: some documentation fixes selftests:firmware: fixes a call to a wrong function name kobject: don't use WARN for registration failures firmware: Fix firmware documentation for recent file renames test_firmware: fix setting old custom fw path back on exit, second try test_firmware: Install all scripts drivers: change struct device_driver::coredump() return type to void
