Hi Tinsae,

sorry for the very late reply.

We don't need this extra flag, we already do this statement in
i2c_register_spd().

Can't we just assume that for spd5118 spd write is always
disabled? That's what happens in i2c_register_spd.

Check:

84d477354b0a ("i2c: smbus: Support DDR5 and LPDDR5 SPD EEPROMs")
4d6d35d3417d ("i2c: smbus: introduce Write Disable-aware SPD instantiating functions")

Thanks,
Andi
