rust: dma: add `Send` implementation for `CoherentAllocation`
Stephen found a future build failure in linux-next [1]:
error[E0277]: `*mut MyStruct` cannot be sent between threads safely
--> samples/rust/rust_dma.rs:47:22
|
47 | impl pci::Driver for DmaSampleDriver {
| ^^^^^^^^^^^^^^^ `*mut MyStruct` cannot be sent between threads safely
It is caused by the interaction between commit 935e1d90bf6f ("rust: pci:
require Send for Driver trait implementers") from the driver-core tree,
which fixes a missing concurrency requirement, and commit 9901addae63b
("samples: rust: add Rust dma test sample driver") which adds a sample
that does not satisfy that requirement.
Add a `Send` implementation to `CoherentAllocation`, which allows the
sample (and other future users) to satisfy it.
