Thank you. This information would be great in the commit message (in the future). […]
It will still work with a standard GNU/Linux distribution. What the patch allows us to do is not spend time on each suspend/resume performing the _ON and _OFF methods on power resources for peripherals that are not actually connected to the device.
Basically, the I2C devices spend a few ms getting probed for their existence or not when the kernel inits the drivers, and then we don't have to waste time on non-existent devices for suspend/resume. On other distributions, suspend/resume might just take a little longer
