[PATCH] ARM:S3C2440: MINI2440 Remove some improper __initdata qualifiers

Hi,all

Since 2.6.31-rc7 released on Aug 22, someone used mini-2440 mach may
find that some device worked improperly and especailly when the machine
power off, some panic message showed up. After some debug work, I found
the bug is caused by the improper __initdata qualifier on some device
drivers. I visted the mini2440 webpage and found Michel Pollet had just
patched for the bug on that day[1].

[1]
http://repo.or.cz/w/linux-2.6/mini2440.git?a=commitdiff;h=e575112de40df34936dbeac1699efc270231a40e

The patch[1] given by Michel is not for the mainline but for his
development tree, so the patch can't be applied directly for the
mainline. Two months has gone, the bug still exsits in the mainline, so
I created a new patch based on 2.6.32-rc5. The patch has been tested on
my mini2440 board.

Best Regards,

Shine
