I'm sure I found a bug in intel8x0.c.
At the end of the function snd_intel8x0_codec_semaphore. If we couldn't get the semaphore in
1 ms, we'll reset the register and return EBUSY. But to reset the register, we should do a
iaputword ( chip, 0, 0 ), according to the datasheet, write any value the this register will reset the
register.
But in the code, what we did is iagetword ( chip, 0 ). This bug hadn't be exclosed because this code
path had never been reached, for the semaphore error often means a hardware error, which is very
rare.
So, is there anybody who can modify this ?
