I removed the genwqe_dprintk function completely. Our debug flag I kept
for the moment, because I like to use the kernel hexdump functions to
print my control blocks for debugging:
if (cd->debug & dbg_card_ddcb) {
dev_dbg(&pci_dev->dev, "FINISHED DDCB#%d\n", req->num);
genwqe_hexdump(pci_dev, pddcb, sizeof(*pddcb));
}
Or is there something allowing me to do those hexdumps with the
dynamic_debug feature too? dynamic_hex_dump() looks like what I want.
So let me try to use that and get rid of my own debug support.
