[PATCH 0/2] sysfs: allow user-space request for devcoredump

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

Arend van Spriel (2):
sysfs: add attribute specification for /sysfs/devices/.../coredump
drivers: base: add coredump driver ops
