[REPOST][TRIVIAL][PATCH 1/1] Fix various section mismatches in 2.6.30-rc7

From: Pranith Kumar
Date: Fri May 29 2009 - 03:25:03 EST


Fix the following section mismatches reported by


For the first warning, intel_lvds_init might get called after module
has been loaded,
intel_no_lvds shouldn't be marked __initdata.

For the others the explanation is in the below warnings.

WARNING: vmlinux.o(.text+0x25ad83): Section mismatch in reference from
the function intel_lvds_init() to the variable
The function intel_lvds_init() references
the variable __initdata intel_no_lvds.
This is often because intel_lvds_init lacks a __initdata
annotation or the annotation of intel_no_lvds is wrong.

WARNING: vmlinux.o(.text+0x26308b): Section mismatch in reference from
the function intel_opregion_free() to the function
The function intel_opregion_free() references a function in an exit section.
Often the function acpi_video_exit() has valid usage outside the exit section
and the fix is to remove the __exit annotation of acpi_video_exit.

WARNING: vmlinux.o(__ksymtab+0x75f0): Section mismatch in reference
from the variable __ksymtab_acpi_video_exit to the function
The symbol acpi_video_exit is exported and annotated __exit
Fix this by removing the __exit annotation of acpi_video_exit or drop
the export.
