I'm sorry, I'll obey the rule from now on.

You're right. I'll revise it.

Understood. But I just tested the set_bias_level() way to handle BIAS,
it prompts "wm8962 0-001a: DC servo timed out" when I start to play a
wav file. There should be still some parts of code not right.
So I'm gonna just revise the comment to continue the resume() methods.
It should be appropriate since pm_suspend() is handling bias-off in
the current code.

If you still can't accept it, I will then trace the code next week.
It's Friday night here, and I'm starving now :(

Thank you,
