From b0ba9720846c980d053b1ffcd766fddfbef95d4c Mon Sep 17 00:00:00 2001 From: Xenia Ragiadakou <burzalodowa@gmail.com> Date: Fri, 15 Nov 2013 05:34:06 +0200 Subject: xhci: replace xhci_readl() with readl() Function xhci_readl() is used to read 32bit xHC registers residing in MMIO address space. It takes as first argument a pointer to the xhci_hcd although it does not use it. xhci_readl() internally simply calls readl(). This creates an illusion that xhci_readl() is an xhci specific function that has to be called in a context where a pointer to xhci_hcd is available. Remove the unnecessary xhci_readl() wrapper function and replace its calls to with calls to readl() to make the code more straightforward.
