From: Mario Limonciello Date: Mon, 7 Apr 2025 18:36:55 +0000 (-0500) Subject: ACPI: Add missing prototype for non CONFIG_SUSPEND/CONFIG_X86 case X-Git-Tag: v6.16-rc1~161^2^3~3 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e1bdbbc98279164d910d2de82a745f090a8b249f;p=thirdparty%2Flinux.git ACPI: Add missing prototype for non CONFIG_SUSPEND/CONFIG_X86 case acpi_register_lps0_dev() and acpi_unregister_lps0_dev() may be used in drivers that don't require CONFIG_SUSPEND or compile on !X86. Add prototypes for those cases.
