[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.
