Claude review: drm/amdgpu/jpeg: Fix format-truncation warning in jpeg_v2_5_sw_init()

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

**Status: Acceptable (minor nit)**

**The type change is well-motivated and correct.** Since `adev->jpeg.num_jpeg_inst` is `uint8_t` (from `amdgpu_jpeg.h:132`), narrowing the loop variable to match is a natural fix. A `uint8_t` value formatted with `%u` produces at most 3 characters ("255"), so `"jpeg_dec_255\0"` = 13 bytes, which comfortably fits in `ring->name[16]`.

**The format specifier change from `%d` to `%u` is correct:**
```c
snprintf(ring->name, sizeof(ring->name), "jpeg_dec_%u", i);
```
Since `i` is now unsigned, `%u` is the matching specifier. Good.

**Minor style nit:** The declaration ordering changed slightly:
```c
	struct amdgpu_ring *ring;
	uint8_t i;
	int r;
	struct amdgpu_device *adev = ip_block->adev;
```
This is fine and follows the existing pattern in the file of grouping declarations by type. No issue here.

**One consideration:** The `harvest_config` mask expression `(1 << i)` at line 112 and 143 is safe with `uint8_t i` — `i` gets integer-promoted and the shift is well-defined for values 0–255 (though in practice `num_jpeg_inst` is small, typically 1–2).

**No functional concerns.** The patch is minimal and solves exactly the reported problem.

Reviewed-by recommendation: **Acceptable as-is.**
