This changed the original behaviour because the re-programming code doesn't take into account the existing value in the register. Both ath9k and ath9k_htc were not affected by this change because the opmode is re-initialized after every reset, when RX is started. Revert to the original behavior, except keep it outside the REGWRITE block. This would help remove extraneous opmode calls in the driver core. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
