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?

module_depend

MODULE_DEPEND(9)					   BSD Kernel Developer's Manual					  MODULE_DEPEND(9)

NAME

     MODULE_DEPEND -- set kernel module dependencies

SYNOPSIS

     #include <sys/param.h>
     #include <sys/module.h>

     MODULE_DEPEND(name, moddepend, int minversion, int prefversion, int maxversion);

DESCRIPTION

     The MODULE_DEPEND() macro sets a dependency on another kernel module with name moddepend, which has registered its version with
     MODULE_VERSION().

     The MODULE_DEPEND() macro provides hints to the kernel loader(8) and to the kernel linker to ensure that the named dependency is loaded prior
     to the existing module.  It does not change or dictate the order in which modules are initialized at runtime.

     Three versions must be specified for moddepend:

     minversion   The minimum version on which the current module can depend.

     maxversion   The maximum version on which the current module can depend.

     prefversion  The preferred version on which the current module can depend.

EXAMPLES

     MODULE_DEPEND(foo, bar, 1, 3, 4);

SEE ALSO

     DECLARE_MODULE(9), module(9), MODULE_VERSION(9)
