dma-mapping: add missing `inline` for `dma_free_attrs`
[ Upstream commit 2cdaff22ed26f1e619aa2b43f27bb84f2c6ef8f8 ]
Under an UML build for an upcoming series [1], I got `-Wstatic-in-inline`
for `dma_free_attrs`:
BINDGEN rust/bindings/bindings_generated.rs - due to target missing
In file included from rust/helpers/helpers.c:59:
rust/helpers/dma.c:17:2: warning: static function 'dma_free_attrs' is used in an inline function with external linkage [-Wstatic-in-inline]
17 | dma_free_attrs(dev, size, cpu_addr, dma_handle, attrs);
| ^
rust/helpers/dma.c:12:1: note: use 'static' to give inline function 'rust_helper_dma_free_attrs' internal linkage
12 | __rust_helper void rust_helper_dma_free_attrs(struct device *dev, size_t size,
| ^
| static
The issue is that `dma_free_attrs` was not marked `inline` when it was
introduced alongside the rest of the stubs.
Thus mark it.
