Merge tag 'driver-core-5.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH: "Here are a number of small driver core fixes for 5.7-rc5 to resolve a bunch of reported issues with the current tree. Biggest here are the reverts and patches from John Stultz to resolve a bunch of deferred probe regressions we have been seeing in 5.7-rc right now. Along with those are some other smaller fixes: - coredump crash fix - devlink fix for when permissive mode was enabled - amba and platform device dma_parms fixes - component error silenced for when deferred probe happens All of these have been in linux-next for a while with no reported issues" * tag 'driver-core-5.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: regulator: Revert "Use driver_deferred_probe_timeout for regulator_init_complete_work" driver core: Ensure wait_for_device_probe() waits until the deferred_probe_timeout fires driver core: Use dev_warn() instead of dev_WARN() for deferred_probe_timeout warnings driver core: Revert default driver_deferred_probe_timeout value to 0 component: Silence bind error on -EPROBE_DEFER driver core: Fix handling of fw_devlink=permissive coredump: fix crash when umh is disabled amba: Initialize dma_parms for amba devices driver core: platform: Initialize dma_parms for platform devices
