Hey again Borislav:
Come to think of it, given this struct:
include/linux/aer.h:struct aer_header_log_regs {
include/linux/aer.h- unsigned int dw0;
include/linux/aer.h- unsigned int dw1;
include/linux/aer.h- unsigned int dw2;
include/linux/aer.h- unsigned int dw3;
include/linux/aer.h-};
this would be a lot more readable as:
static void __print_tlp_header(struct pci_dev *dev,
struct aer_header_log_regs *t)
{
dev_err(&dev->dev, " TLP Header: %08x %08x %08x %08x\n",
tlp->dw0, tlp->dw1, tlp->dw2, tlp->dw3);
}
though if the desire really is to show le output,
maybe these should use:
dev_err(&dev->dev, " TLP Header: %08x %08x %08x %08x\n",
cpu_to_le32(tlp->dw0), cpu_to_le32(tlp->dw1),
cpu_to_le32(tlp->dw2), cpu_to_le32(tlp->dw3));
