Merge tag 'driver-core-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH: "Here are a few small fixes for 4.14-rc4. The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one straggler made it in through some other tree (odds are, one of mine...) So there's a simple removal of the last user, and then finally the macro is removed from the tree. There's a fix for old crazy udev instances that insist on reloading a module when it is removed from the kernel due to the new uevents for bind/unbind. This fixes the reported regression, hopefully some year in the future we can drop the workaround, once users update to the latest version, but I'm not holding my breath. And then there's a build fix for a linker warning, and a buffer overflow fix to match the PCI fixes you took through the PCI tree in the same area. All of these have been in linux-next for a few weeks while I've been traveling, sorry for the delay" * tag 'driver-core-4.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: driver core: remove DRIVER_ATTR fpga: altera-cvp: remove DRIVER_ATTR() usage driver core: platform: Don't read past the end of "driver_override" buffer base: arch_topology: fix section mismatch build warnings driver core: suppress sending MODALIAS in UNBIND uevents

Device drivers can export attributes via their sysfs directories.
-Drivers can declare attributes using a DRIVER_ATTR macro that works
-identically to the DEVICE_ATTR macro.
+Drivers can declare attributes using a DRIVER_ATTR_RW and DRIVER_ATTR_RO

Example:
-DRIVER_ATTR(debug,0644,show_debug,store_debug);

This is equivalent to declaring:
