[ Upstream commit a28206060dc5848a1a2a15b7f6ac6223d869084d ]

Similar to many other Lenovo models with AMD chips, the Lenovo
Yoga Pro 7 14ASP9 (product name 83HN) requires a specific quirk
to ensure internal mic detection. This patch adds a quirk fixing this.

Based on my analysis of the commit and comparison with the similar
historical commits, here is my assessment: **YES** This commit should be
backported to stable kernel trees for the following reasons: ## Code
Analysis **1. Nature of the Change:** The commit adds a single quirk
entry for the Lenovo Yoga Pro 7 14ASP9 (product name "83HN") to the
`yc_acp_quirk_table[]` array in `sound/soc/amd/yc/acp6x-mach.c`. The
change is minimal and contained: ```c + { + .driver_data = &acp6x_card,
+ .matches = { + DMI_MATCH(DMI_BOARD_VENDOR, "LENOVO"), +
DMI_MATCH(DMI_PRODUCT_NAME, "83HN"), + } + }, ``` **2. Meets Stable Tree
Criteria:** - **Device ID Addition**: This is explicitly mentioned in
the stable kernel rules as acceptable - "It must either fix a real bug
that bothers people or just add a device ID" - **Under 100 lines**: The
change is only 7 lines with context - **Obviously correct**: The pattern
matches exactly what's used for dozens of other Lenovo models - **Fixes
real user issue**: Internal microphone non-functionality is a clear
hardware regression/bug that affects users **3. Historical Precedent:**
All 5 similar commits provided as examples received "Backport Status:
YES". They all follow the exact same pattern: - Similar commit subjects
mentioning specific Lenovo models - Identical code structure adding DMI
quirk entries - Same commit messages describing microphone functionality
fixes - Several explicitly included `Cc: stable@vger.kernel.org` tags
**4. Risk Assessment:** - **Minimal regression risk**: Adding a quirk
entry cannot break existing functionality - **Contained change**: Only
affects the specific Lenovo model 83HN - **Well-established pattern**:
This quirk mechanism is proven stable across dozens of similar entries
**5. User Impact:** The commit message clearly states this fixes
internal microphone detection on a specific laptop model. Non-functional
audio hardware represents a significant user-facing issue that stable
trees are meant to address. **6. Code Quality:** The change also
includes a minor whitespace fix (replacing spaces with tab for
consistency), showing attention to code quality without introducing
functional changes. This commit perfectly matches the stable tree
criteria: it's a small, safe device ID addition that fixes a real user-
affecting hardware issue with minimal risk of regression.
