2025-03-19wifi: mt76: mt7921: fix kernel panic due to null pointer dereferenceMing Yen Hsieh
Address a kernel panic caused by a null pointer dereference in the `mt792x_rx_get_wcid` function. The issue arises because the `deflink` structure is not properly initialized with the `sta` context. This patch ensures that the `deflink` structure is correctly linked to the `sta` context, preventing the null pointer dereference.

Assuming sums of values stored in variables such as sub_total_cnt and total_ppdu_cnt are big enough to warrant their u64 type, it makes sense to ensure that their calculation takes into account possible integer overflow issues. Play it safe and fix the problem by casting right hand expressions to u64 as well. Also, slightly adjust tabulation.

2025-03-19wifi: mt76: mt7925: fix fails to enter low power mode in suspend stateQuan Zhou
The mt7925 sometimes fails to enter low power mode during suspend. This is caused by the chip firmware sending an additional ACK event to the host after processing the suspend command. Due to timing issues, this event may not reach the host, causing the chip to get stuck. To resolve this, the ACK flag in the suspend command is removed, as it is not needed in the MT7925 architecture. This prevents the firmware from sending the additional ACK event, ensuring the device can reliably enter low power mode during suspend.
