Hi,

We got some machines like Acer desktop equipped with NVIDIA GTX 1660
card, Acer Predator PH315-52 equipped with NVIDIA GeForce RTX 2060
Mobile and ASUS UX581LV equipped with NNVIDIA GeForce RTX 2060.
We found them take long time (more than 50 seconds) to resume after
suspend.  During the resuming time, the screen is blank.  And check
the dmesg, found the error during resume:

You are using an outdated kernel, 5.4.0. Please make sure that you can
reproduce the issue with mainline, or at least with the longterm
5.4.x.

Ajay, based on the backtrace, the issue seems to be starting from your
I2C driver. Please take a look at this.

I meant the latest 5.4.x, which today is 5.4.29.
