Rather than arguing over whether we have to have sparse clean code, I
decided to annotate the code myself. Here's a patch that fixes most
of the sparse warnings in the nes driver. There's still some stuff
that actually looks buggy, like the way hte_index stuff is handled.
You initialize hte_index_mask as:
hte_index_mask = ((u32)1 << ((u32temp & 0x001f)+1))-1;
nesadapter->hte_index_mask = hte_index_mask;
but then compute hte_index stuff with:
nesqp->hte_index = cpu_to_be32(
crc32c(~0, (void *)&nes_quad, sizeof(nes_quad)) ^
0xffffffff);
and then do:
nesqp->hte_index &= nesadapter->hte_index_mask;
which seems odd to say the least (hte_index is big-endian,
hte_index_mask is cpu-endian).
And also, there's code with the loc_addr/rem_addr etc that seem very
confused. For example
cm_info->loc_addr = htonl(cm_info->loc_addr);
cm_info->rem_addr = htonl(cm_info->rem_addr);
cm_info->loc_port = htons(cm_info->loc_port);
cm_info->rem_port = htons(cm_info->rem_port);
which is obviously impossible to annotate correctly, and I couldn't
keep track of the endianness stuff elsewhere.
Anyway this is what I have in case the promised cleanups don't turn up
in time...
