[CentOS] Module.symvers

I am going into:
/usr/src/kernels/2.6.18-92.1.10.el5-x86_64

and doing a "make mrproper"
attempting to rebuild the Modules.symvers file. As I added ALSA 1.0.17  
to the current kernel.

I am getting an error:
 make mrproper
scripts/Makefile.clean:17: 
/usr/src/kernels/2.6.18-92.1.10.el5-x86_64/drivers/infiniband/hw/amso1100/Makefile: 
No such file or directory
make[3]: *** No rule to make target 
`/usr/src/kernels/2.6.18-92.1.10.el5-x86_64/drivers/infiniband/hw/amso1100/Makefile'.  
Stop.
make[2]: *** [drivers/infiniband/hw/amso1100] Error 2
make[1]: *** [drivers/infiniband] Error 2
make: *** [_clean_drivers] Error 2

Is this not the correct way to rebuild the Modules.symvers file?
