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 935e1d9 ("rust: pci: require Send for Driver trait implementers") from the driver-core tree, which fixes a missing concurrency requirement, and commit 9901add ("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.
