X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=291a73c9be15f12046a7291ec0bf7176a58d4f14;p=linux-beck.git

ACPI / PM: Do not save/restore NVS on Sony Vaio VGN-NW130D

The saving of the NVS memory area during suspend and restoring it
during resume causes problems to appear on Sony Vaio VGN-NW130D, so
blacklist that machine to avoid those problems.
