[PATCH] rust: pci: use c_* types via kernel prelude

From: herculoxz
Date: Mon Jul 28 2025 - 20:32:12 EST


From: Abhinav Ananthu <abhinav.ogl@xxxxxxxxx>

Update PCI FFI callback signatures to use from the ,
instead of accessing it via . This aligns with the Rust-for-Linux coding
guidelines and ensures ABI correctness when interfacing with C code.
