Hi guys,
Currently I'm experiencing long time latency of resuming
from S3 on my MacBookPro 2015, according to the log of ftrace,
one of the suspicious time consumers is ax88772a_hw_reset has an
explicit msleep of 200ms in the code, is this mandatory or
can we reduce this sleep time of it?

Thanks in advance,
Yu
