[PATCH] clocksource: acpi_pm: add another greylist chipset
I have an acpi_pm that goes backwards, but it's not intel. I tested the
verified read and my acpi_pm started to function properly. So I added it
to the greylist. I'm assuming that's the right spot.
I also added an unlikely() to the while, cause it seems appropriate.
