Why I did it
Kernel5.10 pca954x drv deselect is disable, it provide user to set via idle_state to "-2".
If deselect is disable, some device will get error when pca channel is not closed.
How I did it
Input "-2" to /sys/bus/i2c/drivers/pca954x/-00/idle_state.
How to verify it
Test to get fan or psu sysfs, it will not data.
After set "-2" to idle_state, all sysf work well.
Which release branch to backport (provide reason below if selected)
