Subject: [PATCH] acpi: arm64: fix section mismatch warning
Date: Mon, 27 Sep 2021 16:19:14 +0200 [thread overview]
Message-ID: <20210927141921.1760209-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
In a gcc-11 randconfig build I came across this warning:
WARNING: modpost: vmlinux.o(.text.unlikely+0x2c084): Section mismatch in reference from the function next_platform_timer() to the variable .init.data:acpi_gtdt_desc
The function next_platform_timer() references
the variable __initdata acpi_gtdt_desc.
This is often because next_platform_timer lacks a __initdata
annotation or the annotation of acpi_gtdt_desc is wrong.
This happens when next_platform_timer() fails to get inlined
despite the inline annotation. Adding '__init' solves the issue,
and it seems best to remove the 'inline' in the process seems
better anyway.
