Add the board to the WMI monitoring list.

The commit message explains that this ASUS motherboard has an nct6775 hardware monitoring chip, but it cannot be used by default due to a resource conflict with WMI methods. Adding the board to the WMI monitoring list resolves this conflict and enables hardware monitoring. ### Code Change Analysis The change is a **single line addition** — inserting one string into an alphabetically sorted list of board names: ```c "Pro WS WRX90E-SAGE SE", ``` This is inserted between "Pro WS W790E-SAGE SE" and "ProArt B650-CREATOR", maintaining alphabetical order. No logic changes, no new functions, no structural modifications. ### Classification: Hardware Quirk / Device ID Addition This falls squarely into the **"hardware quirks/workarounds"** exception category for stable backports. The `asus_msi_boards[]` list is effectively a board-level quirk table that tells the driver to use WMI- based monitoring instead of direct I/O, resolving the resource conflict. Without this entry, users of this specific motherboard cannot use hardware monitoring at all. ### Stability Indicators - **Tested-by:** Marcus confirmed the fix works on the actual hardware - **Bug report link:** https://bugzilla.kernel.org/show_bug.cgi?id=204807 — this is a documented real-world issue - **Reviewed and merged by:** Guenter Roeck, the hwmon subsystem maintainer - **Pattern:** Identical to dozens of other board additions in this same file that have been backported to stable ### Risk Assessment - **Risk: Extremely low.** Adding a string to a board match list cannot affect any other board or any other code path. The match is exact — only the "Pro WS WRX90E-SAGE SE" board is affected. - **Scope:** Single line in a single file - **Dependencies:** None — the WMI monitoring infrastructure already exists in stable trees - **Regression potential:** Essentially zero ### User Impact Without this fix, users of the ASUS Pro WS WRX90E-SAGE SE motherboard (a workstation-class board) have no hardware monitoring capability. This is a real user-reported bug (kernel bugzilla #204807) with a tested fix. ### Stable Criteria Check 1. **Obviously correct and tested:** Yes — single string addition, tested by user 2. **Fixes a real bug:** Yes — hardware monitoring doesn't work without it 3. **Important issue:** Yes — complete loss of hwmon functionality for this board 4. **Small and contained:** Yes — one line 5. **No new features:** Correct — enables existing functionality on specific hardware 6. **Applies cleanly:** Very likely — it's a simple list insertion **YES** drivers/hwmon/nct6775-platform.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/hwmon/nct6775-platform.c b/drivers/hwmon/nct6775-platform.c index c3a719aef1ace..555029dfe713f 100644 --- a/drivers/hwmon/nct6775-platform.c +++ b/drivers/hwmon/nct6775-platform.c @@ -1357,6 +1357,7 @@ static const char * const asus_msi_boards[] = { "Pro WS W680-ACE IPMI", "Pro WS W790-ACE", "Pro WS W790E-SAGE SE", + "Pro WS WRX90E-SAGE SE", "ProArt B650-CREATOR", "ProArt B660-CREATOR D4", "ProArt B760-CREATOR D4", -- 2.51.0
