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. Signed-off-by: Arend van Spriel <aspriel@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

+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.
