From 204b7793f2a9935e9a08524d0b4bb51b990d518e Mon Sep 17 00:00:00 2001 From: Xenia Ragiadakou Date: Fri, 15 Nov 2013 05:34:07 +0200 Subject: xhci: replace xhci_writel() with writel() Function xhci_writel() is used to write a 32bit value in 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_writel() internally simply calls writel(). This creates an illusion that xhci_writel() is an xhci specific function that has to be called in a context where a pointer to xhci_hcd is available. Remove xhci_writel() wrapper function and replace its calls with calls to writel() to make the code more straight-forward.
