kobject: return error code if writing /sys/.../uevent fails ...
[ Upstream commit df44b479654f62b478c18ee4d8bc4e9f897a9844 ]
Propagate error code back to userspace if writing the /sys/.../uevent
file fails. Before, the write operation always returned with success,
even if we failed to recognize the input string or if we failed to
generate the uevent itself.
With the error codes properly propagated back to userspace, we are
able to react in userspace accordingly by not assuming and awaiting
a uevent that is not delivered.
