No, while sending the patch I partially compiled it 
`make drivers/staging/rtl8192e` but when I fully compile it `make all` it gives 
me the same error. It is a mistake on my part.

I was not aware of this and assumed that ideally the driver has only one (PCI) 
interface so all the files should be compiled into one `.ko` file and loaded.

Yes, this makes sense now. 

Moving forward, 
Dan, Greg and Philipp what would be the best fix for this issue, 
1.  Patchset to combine both the modules into one module 
2.  Revert back this patchset to v1.

Looking forward for your response.
