Arend van Spriel 36d1d09af1 sysfs: add attribute specification for /sysfs/devices/.../coredump 
This patch adds the specification for /sysfs/devices/.../coredump
which allows user-space to trigger a device coredump obtaining
binary data from the device for (fault) analysis. It relies on
CONFIG_DEV_COREDUMP being enabled.

What: /sys/devices/.../coredump Date: December 2017 Contact: Arend van Spriel aspriel@gmail.com Description: The /sys/devices/.../coredump attribute is only present when the device is bound to a driver, which provides the .coredump() callback. The attribute is write only. Anything written to this file will trigger the .coredump() callback.

	Available when CONFIG_DEV_COREDUMP is enabled.
