From: Arend van Spriel <aspr...@gmail.com>
Since commit 833c95456a70 ("device coredump: add new device coredump class")
device drivers have a unified way to provide binary data obtained from a
failing_device to user-space. However, there may be use-cases in which the
driver has no reason to obtain the data, but user-space wants to initiate
it. This adds a coredump device attribute in sysfs when the driver bound to
the device supports the newly added coredump driver callback.
These patches apply to the driver-core-next branch of the driver-core
repository.
