This is a single-patch series that fixes a `-Wformat-truncation` compiler warning in `jpeg_v2_5_sw_init()`. The warning arises because GCC can't prove that the loop variable `i` (declared as `int`) will always fit within the remaining buffer space of `ring->name[16]` when formatted as `"jpeg_dec_%d"` (prefix is 9 chars + NUL = at most 6 chars for the number, but a full `int` could be 11 digits plus a sign).

The fix narrows the loop variable `i` from `int` to `uint8_t` and changes the format specifier from `%d` to `%u`. This is correct and consistent: `num_jpeg_inst` is already declared as `uint8_t` in `amdgpu_jpeg.h:132`, so the loop counter can never exceed 255, which is at most 3 digits — well within the buffer.

**Verdict: Looks good.** The fix is minimal, correct, and addresses the root cause rather than papering over it with a cast or pragma. One minor style nit below.
