Subject: ACPI: resolve GPE immediate wakeup regression
From: Alexey Starikovskiy <[EMAIL PROTECTED]>
Removing disabling of GPEs from enter_sleep function causes regression on
nx6125.
Doing disable_all_gpes both in prepare to sleep and in enter sleep resolves
regression,
while still fixes Acer notebooks.
