From: Len Brown Date: Wed, 25 Jul 2007 02:26:33 +0000 (-0400) Subject: ACPI: Kconfig: remove CONFIG_ACPI_SLEEP from source X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e8b2fd01228f690c3e0cb3f14facfa8d93d4adae;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git ACPI: Kconfig: remove CONFIG_ACPI_SLEEP from source As it was a synonym for (CONFIG_ACPI && CONFIG_X86), the ifdefs for it were more clutter than they were worth. For ia64, just add a few stubs in anticipation of future S3 or S4 support.
