In 32-bit arm, the build fails with:
error[E0308]: mismatched types
--> drivers/gpu/drm/nova/file.rs:42:28
|
42 | getparam.set_value(value);
| --------- ^^^^^ expected `u64`, found `u32`
| |
| arguments to this method are incorrect
|
note: method defined here
--> drivers/gpu/drm/nova/uapi.rs:29:12
|
29 | pub fn set_value(&self, v: u64) {
| ^^^^^^^^^ ------
help: you can convert a `u32` to a `u64`
|
42 | getparam.set_value(value.into());
| +++++++
The reason is that `Getparam::set_value` takes a `u64` (from the UAPI),
but `pci::Device::resource_len()` returns a `resource_size_t`, which is a
`phys_addr_t`, which may be 32- or 64-bit.
Thus add an `into()` call to support the 32-bit case, while allowing the
Clippy lint that complains in the 64-bit case where the type is the same.
