Since each driver will use it's own reg read/write functions (ath5k hwcode still uses ath5k_hw_reg_read/write), why do we need to havecommon reg read/write functions like that used in the driver code ?This makes the code more complex that it needs to be and i don't see areason why we need it. I understand why we need a way to handleread/write functions from common ath code but i don't see a reason touse these functions on ath5k, we can just fill ath_ops struct so thatcommon code can use them and leave ath5k_hw_read/write untouched.
