Hello Shayne Chen,

The patch 98686cd21624: "wifi: mt76: mt7996: add driver for MediaTek
Wi-Fi 7 (802.11be) devices" from Nov 22, 2022, leads to the following
Smatch static checker warning:

	drivers/net/wireless/mediatek/mt76/mt7996/debugfs.c:657 mt7996_rf_regval_set()
	warn: passing casted pointer '&val' to 'mt7996_mcu_rf_regval()' 64 vs 32.

drivers/net/wireless/mediatek/mt76/mt7996/debugfs.c
    652 static int
    653 mt7996_rf_regval_set(void *data, u64 val)
    654 {
    655         struct mt7996_dev *dev = data;
    656 
--> 657         return mt7996_mcu_rf_regval(dev, dev->mt76.debugfs_reg, (u32 *)&val, true);
                                                                        ^^^^^^^^^^^
This code only "works" on little endian systems.  You have to do
something like:

	u32 u32_val = val;

	return mt7996_mcu_rf_regval(dev, dev->mt76.debugfs_reg, &u32_val, true);

    658 }
