Merge tag 'driver-core-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg Kroah-Hartman: "Here is the big driver core update for 5.4-rc1. There was a bit of a churn in here, with a number of core and OF platform patches being added to the tree, and then after much discussion and review and a day-long in-person meeting, they were decided to be reverted and a new set of patches is currently being reviewed on the mailing list. Other than that churn, there are two "persistent" branches in here that other trees will be pulling in as well during the merge window. One branch to add support for drivers to have the driver core automatically add sysfs attribute files when a driver is bound to a device so that the driver doesn't have to manually do it (and then clean it up, as it always gets it wrong). There's another branch in here for generic lookup helpers for the driver core that lots of busses are starting to use. That's the majority of the non-driver-core changes in this patch series. There's also some on-going debugfs file creation cleanup that has been slowly happening over the past few releases, with the goal to hopefully get that done sometime next year. All of these have been in linux-next for a while now with no reported issues" [ Note that the above-mentioned generic lookup helpers branch was already brought in by the LED merge (commit 4feaab05dc1e) that had shared it. Also note that that common branch introduced an i2c bug due to a bad conversion, which got fixed here. - Linus ] * tag 'driver-core-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (49 commits) coccinelle: platform_get_irq: Fix parse error driver-core: add include guard to linux/container.h sysfs: add BIN_ATTR_WO() macro driver core: platform: Export platform_get_irq_optional() hwmon: pwm-fan: Use platform_get_irq_optional() driver core: platform: Introduce platform_get_irq_optional() Revert "driver core: Add support for linking devices during device addition" Revert "driver core: Add edit_links() callback for drivers" Revert "of/platform: Add functional dependency link from DT bindings" Revert "driver core: Add sync_state driver/bus callback" Revert "of/platform: Pause/resume sync state during init and of_platform_populate()" Revert "of/platform: Create device links for all child-supplier depencencies" Revert "of/platform: Don't create device links for default busses" Revert "of/platform: Fix fn definitons for of_link_is_valid() and of_link_property()" Revert "of/platform: Fix device_links_supplier_sync_state_resume() warning" Revert "of/platform: Disable generic device linking code for PowerPC" devcoredump: fix typo in comment devcoredump: use memory_read_from_buffer of/platform: Disable generic device linking code for PowerPC device.h: Fix warnings for mismatched parameter names in comments ...
