This is a single-patch fix for a real integer truncation bug in the Intel VPU (IVPU) IPC receive path. The issue is well-identified: `min_t(int, ...)` casts a `u32` value (`data_size`) to `signed int`, which means values >= 0x80000000 become negative. When that negative value is then used as a `u32` (the type of `size`), it wraps to a very large unsigned value, leading to an oversized `memcpy` at line 291 that could overflow a stack buffer.

The fix is correct and minimal — replacing `min_t(int, ...)` with `min()` — since both operands (`data_size` is `u32`, `sizeof(...)` is `size_t`) are unsigned, making `min()` safe and appropriate here. The Fixes tag, stable backport annotation, and commit message are all well-formed.

**Verdict: This patch looks correct and ready to merge.**
