Subject: Sparse 0.2 warnings from {asm,net}/checksum.h

With sparse 0.2, my previously sparse-clean driver generates the
following warnings:

include/asm/checksum.h:182:6: warning: symbol 'sum' shadows an earlier one
include/asm/checksum.h:178:28: originally declared here
include/net/checksum.h:33:6: warning: symbol 'sum' shadows an earlier one
include/net/checksum.h:31:27: originally declared here

Architecture is i386. The lines referred to are in the functions
csum_and_copy_to_user() and csum_and_copy_from_user(), but I
don't see why sparse would emit such a warning for that code.

Any chance of getting rid of these?

Thanks
Tilman
