After changing the do_install () in mymodule.bb like this:

        install -d ${D}/lib/modules/${KERNEL_VERSION}

#install -d ${D}/lib/modules/${KERNEL_VERSION}</font>

        install -m 0755 ${B}/kernel_module_example.ko ${D}/lib/modules/${KERNEL_VERSION}/

#install -m 0755 ${B}/kernel_module_example.ko ${D}/lib/modules/${KERNEL_VERSION}/</font>

it works fine.
