[PATCH 1/1] devtmpfs: Fix section mismatch warning

From: Harvey Yang
Date: Sat Aug 20 2011 - 22:45:31 EST


drivers/base/built-in.o(.text+0xe554): Section mismatch in reference f
rom the function devtmpfsd() to the variable .init.data:setup_done
The function devtmpfsd() references
the variable __initdata setup_done.
This is often because devtmpfsd lacks a __initdata
annotation or the annotation of setup_done is wrong.

"setup_done" is not used after init. but putting it into initdata section leads a section mismatch warning, so initialize it dynamically in __init function.
