Bug description:
[Impact]
It drains power more than 0.5 Watt after power off(S5) the machine with QCA9377 wifi card. The power consumption should be lower than 0.5 Watt, or it won't pass E-star 7.

Qualcomm provides this fix, and the power consumption becomes 0.23 Watt at S5. This fix doesn't submit to upstream yet, Qualcomm is still working on it.

[Test]
Verified on Dell machines, it works.

[Regression Potential]
Low.
