Claude review: drm/imx/dcss: add missing kernel-doc parameters for scaler functions

Patch Review

**Correctness: Good.** Both additions match the actual function signatures.

For `dcss_scaler_gaussian_filter()` (line 171–173 of `dcss-scaler.c`):
```c
static void dcss_scaler_gaussian_filter(int fc_q, bool use_5_taps,
					bool phase0_identity,
					int coef[][PSC_NUM_TAPS])
```
The parameter `phase0_identity` was indeed undocumented and sits between `use_5_taps` and `coef`. The patch correctly inserts `@phase0_identity` in the right position:
```
+ * @phase0_identity: use identity filter for phase 0
```

For `dcss_scaler_filter_design()` (lines 267–270):
```c
static void dcss_scaler_filter_design(int src_length, int dst_length,
				      bool use_5_taps, bool phase0_identity,
				      int coef[][PSC_NUM_TAPS],
				      bool nn_interpolation)
```
Both `phase0_identity` and `nn_interpolation` were missing. The patch adds them in the correct order matching the function signature:
```
+ * @phase0_identity: use identity filter for phase 0
  * @coef: output coefficients
+ * @nn_interpolation: use nearest neighbor interpolation
```

**Minor nit:** The `Assisted-by:` tag in the commit message (`Assisted-by: Opencode:Big-pickle`) is not a standard kernel tag. The kernel community does not have a formally accepted `Assisted-by:` trailer. If this is intended to credit AI assistance, there's currently no agreed-upon convention for this in the kernel. Maintainers may want the author to drop this tag or use a different approach per subsystem policy.

**Verdict:** Trivially correct doc fix. No functional code changes. Looks good to apply, modulo the non-standard tag question.
