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?

modinfo(8)						      System Manager's Manual							modinfo(8)

NAME
modinfo -- program to show information about a Linux Kernel module SYNOPSIS
modinfo [-0] [-F field] [-k kernel] [modulename|filename ...] modinfo -V modinfo -h DESCRIPTION
modinfo extracts information from the Linux Kernel modules given on the command line. If the module name is not a filename, then the /lib/modules/version directory is searched, as is also done by modprobe(8) when loading kernel modules. modinfo by default lists each attribute of the module in form fieldname : value, for easy reading. The filename is listed the same way (although it's not really an attribute). This version of modinfo can understand modules of any Linux Kernel architecture. OPTIONS
-V --version Print the modinfo version. -F --field Only print this field value, one per line. This is most useful for scripts. Field names are case-insenitive. Common fields (which may not be in every module) include author, description, license, parm, depends, and alias. There are often multiple parm, alias and depends fields. The special field filename lists the filename of the module. -k kernel Provide information about a kernel other than the running one. This is particularly useful for distributions needing to extract information from a newly installed (but not yet running) set of kernel modules. For example, you wish to find which firmware files are needed by various modules in a new kernel for which you must make an initrd/initramfs image prior to booting. -0 --null Use the ASCII zero character to separate field values, instead of a new line. This is useful for scripts, since a new line can theoretically appear inside a field. -a -d -l -p -n These are shortcuts for author, description, license. parm and filename respectively, to ease the transition from the old modu- tils modinfo.
