From 6c3ca6654a74dd396bc477839ba8d9792eced441 Mon Sep 17 00:00:00 2001 From: Tiezhu Yang Date: Mon, 3 Jun 2024 15:45:53 +0800 Subject: [PATCH] LoongArch: Remove CONFIG_ACPI_TABLE_UPGRADE in platform_init() Both acpi_table_upgrade() and acpi_boot_table_init() are defined as empty functions under !CONFIG_ACPI_TABLE_UPGRADE and !CONFIG_ACPI in include/linux/acpi.h, there are no implicit declaration errors with various configs. #ifdef CONFIG_ACPI_TABLE_UPGRADE void acpi_table_upgrade(void); #else static inline void acpi_table_upgrade(void) { } #endif #ifdef CONFIG_ACPI ... void acpi_boot_table_init (void); ... #else /* !CONFIG_ACPI */ ... static inline void acpi_boot_table_init(void) { } ... #endif /* !CONFIG_ACPI */ As Huacai suggested, CONFIG_ACPI_TABLE_UPGRADE is ugly and not necessary here, just remove it. At the same time, just keep CONFIG_ACPI to prevent potential build errors in future, and give a signal to indicate the code is ACPI-specific. For the same reason, we also put acpi_table_upgrade() under CONFIG_ACPI.
