void snd_ac97_write(struct snd_ac97 *  ac97 , unsigned short  reg , unsigned short  value );

ac97
    the ac97 instance

reg
    the register to change

value
    the value to set

Writes a value on the given register. This will invoke the write callback directly after the register check. This function doesnAqt change the register cache unlike #snd_ca97_write_cache, so use this only when you donAqt want to reflect the change to the suspend/resume state.
