    Subject[PATCH 5.10 095/103] acpi/arm64: fix next_platform_timer() section mismatch error
    Date
    From: Jackie Liu <liuyun01@kylinos.cn>

    commit 596143e3aec35c93508d6b7a05ddc999ee209b61 upstream.

    Fix modpost Section mismatch error in next_platform_timer().

    [...]
    WARNING: modpost: vmlinux.o(.text.unlikely+0x26e60): 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.

    WARNING: modpost: vmlinux.o(.text.unlikely+0x26e64): 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.

    ERROR: modpost: Section mismatches detected.
    Set CONFIG_SECTION_MISMATCH_WARN_ONLY=y to allow them.
