6.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Danilo Krummrich dakr@kernel.org
commit 935e1d90bf6f14cd190b3a95f3cbf7e298123043 upstream.
The instance of Self, returned and created by Driver::probe() is dropped in the bus' remove() callback.
Request implementers of the Driver trait to implement Send, since the remove() callback is not guaranteed to run from the same thread as probe().
