Hi Kumar, I was waiting until after the 3.12 merge window to queue this patch, but Xenia noticed that the xhci_readl functions can completely go away and be replaced by standard readl/writel operations. She's posted a patchset to do that: http://marc.info/?l=linux-usb&m=137874983529708&w=2 I hate to do this to you, but her patch is a better improvement, so I'll be taking that series instead of your patch. I hope you can still find other clean up work to do in the xHCI driver and USB core. :) Sarah Sharp On Wed, Sep 04, 2013 at 11:42:33AM +0530, Kumar Gaurav wrote: > On Tuesday 03 September 2013 09:34 PM, Sarah Sharp wrote: > >I'm confused.
