insmod: Invalid module format error

I have open suse kernel kernel 3.1.0-1.2-desktop on which I used kernel source 3.1.10-1.2 downloaded from kernel.org.

The module gets built.
While loading a kernel module I am getting Invalid module format error with description "first_driver: no symbol version for module_layout"

The following are the logs:

Code:

linux-k2kj:/home/rkpsuse/FirstDriver # insmod first_driver.ko 
insmod: error inserting 'first_driver.ko': -1 Invalid module format

linux-k2kj:/home/rkpsuse/FirstDriver # modinfo first_driver.ko 
filename:       first_driver.ko
description:    My First Driver
author:         Emertxe Info. Tech
license:        GPL
srcversion:     C4CCFC5DA59927FA4A479E6
depends:        
vermagic:       3.1.10-1.2-desktop SMP preempt mod_unload modversions 686 

linux-k2kj:/home/rkpsuse/FirstDriver # uname -r
3.1.0-1.2-desktop

dmesg
first_driver: no symbol version for module_layout

I guess this is because of mismatching kernel versions.

Cannot I use kernel source 3.1.10-1.2-desktop on kernel 3.1.0-1.2-desktop?
Where can I get the kernel source for 3.1.0-1.2-desktop

How to resolve this issue?

ksyms

KSYMS(8)						       Linux Module Support							  KSYMS(8)

NAME

       ksyms - display exported kernel symbols.

SYNOPSIS

       ksyms [-ahm]

DESCRIPTION

       Ksyms shows information about exported kernel symbols.  The format is address, name, and defining module.

   OPTIONS
       -a, --all
	      Display all symbols.  By default, symbols from the kernel proper are suppressed.

       -h, --noheader
	      Suppress the column header.

       -H, --help
	      Display a summary of options and exit.

       -m, --info
	      Display module information.  Includes each module's kernel load address and size in the listing.

       -V, --version
	      Display the version of ksyms.

SEE ALSO

       insmod(8), modprobe(8), depmod(8), rmmod(8), lsmod(8).

BUGS

       ksyms [ -V | --version ] should exit immediately.  Instead, it prints the version information and behaves as if no options were given.

HISTORY

       The ksyms command was first conceived by Bjorn Ekwall <bj0rn@blox.se>
       The '-m' option was inspired by David Hinds <dhinds@allegro.stanford.edu>
       Updated for 2.1.17 by Richard Henderson <rth@tamu.edu>
