Hi Murali,

Building an ARM 'allmodconfig' kernel now runs into two separate problems
from your driver:

- you have two module_init() instances in one module, which conflict.

- you have two files that are linked into more than one module, so building
  both TI_CPSW and TI_KEYSTONE_NETCP in the same kernel fails.

The answer to both of these is probably to have separate loadable modules,
but you might be able to come up with a different solution.
