Depmod - unresolved symbols in rt73 module

I'm trying to install a linux driver for my wireless network card (D-Link DWL-G510) on my Red Hat Linux 7.1 machine with a 2.4.37.9 kernel. I downloaded the serial monkey driver from the sourceforge site and was able to successfully compile the module. However, whenever I do a "make install", the make script executes a "depmod -a" command which then complains with the message: "Unresolved symbols in /lib/modules/2.4.37.9/extra/rt73.o".

I then 开发者_开发问答executed a "depmod -e" command to show unresolved symbols and it indicates the following information:

request_firmware_Rsmp_38ce5074

release_firmware_Rsmp_33934162

I did a grep on the above information and it showed no source files making reference to it. I searched for it on google and it returned no results. Can anyone help?

I found out the reason - it was missing the firmware_class module. I had to rebuild kernel modules with the experimental feature CONFIG_FW_LOADER as a module which is found under Library routines\Hotplug firmware loading support. After loading the firmware_class module, the rt73 module loaded successfully also.
