Hi Sarah,
I was just reading through xhci driver's code and found something
which i'm unable to understand use of.
Please help me understanding them
1.use of struct xhci_hcd in function xhci_readl
function definition doesn't uses this type of argument
static inline unsigned int xhci_readl(const struct xhci_hcd *xhci,__le32
__iomem *regs)
{
return readl(regs);
}
The function used to print when registers were read, and thus needed the
xhci_hcd argument. It's no longer used, so if you want to submit a
patch to remove that argument, I would take it. Please look at
Documentation/SubmittingPatches if you've never submitted a Linux kernel
patch before.

Please correct me if i'm wrong, as far as i read "*regs" points to the
location of register to be read. Then what is use of xhci_hcd?
I'll be sending patch for the same.
Regards
Kumar gaurav
