## Analysis

### What the commit does
This adds a single DMI quirk entry for the Alienware Area 51 (2025) with
SKU "0CCD" to the SOF SoundWire quirk table. It enables
`SOC_SDW_CODEC_SPKR` for this specific hardware, which is needed for the
speaker codec to function. The commit explicitly references a companion
commit (1b03391d073d) that added the same quirk for the "0CCC" SKU of
the same laptop model.

### Classification: Hardware Quirk Addition
This falls squarely into the **"QUIRKS and WORKAROUNDS"** exception
category for stable backports:
- It's a trivial addition of a DMI match entry to an existing quirk
  table
- The driver and quirk infrastructure already exist in stable
- Without this quirk, audio speakers won't work on this specific laptop
  SKU
- The change is 8 lines of a new table entry, identical in structure to
  dozens of existing entries

### Code change analysis
The diff adds one new `dmi_system_id` struct to the
`sof_sdw_quirk_table[]` array, matching:
- Vendor: "Alienware"
- Product SKU: "0CCD" (exact match)
- Quirk: `SOC_SDW_CODEC_SPKR`

This is identical in structure to the immediately preceding entry for
SKU "0CCC" and many other Dell/Alienware entries in the same table.

### Risk assessment
- **Risk: Extremely low** — The entry only matches one specific DMI SKU,
  so it cannot affect any other hardware
- **Scope: Minimal** — 8 lines added to a data table, no logic changes
- **Tested: Yes** — The commit has a Tested-by tag from the
  author/reporter
- **Benefit: High for affected users** — Without this, speakers don't
  work on this laptop

### Stable criteria
- Obviously correct: Yes (copy of adjacent entry with different SKU)
- Fixes real bug: Yes (no audio output from speakers on this hardware)
- Small and contained: Yes (8-line table entry addition)
- No new features: Correct (enables existing driver functionality on new
  hardware)

### Verification
- The diff shows the new entry is structurally identical to the adjacent
  0CCC SKU entry, confirming it's a straightforward quirk addition
- The commit message references companion commit 1b03391d073d for the
  0CCC SKU, establishing precedent
- The Tested-by tag from the submitter confirms the fix works on real
  hardware
- The change only touches the `sof_sdw_quirk_table[]` DMI table in
  `sound/soc/intel/boards/sof_sdw.c`, no logic changes
- The `SOC_SDW_CODEC_SPKR` quirk value is already used by many other
  entries in the same table, so it's well-established functionality

This is a textbook stable backport candidate — a hardware quirk that
makes speakers work on a specific laptop with zero risk to any other
system.

**YES**
