From c50a00f8feba42c5bccff47e052e4cb0c95dcd2b Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Tue, 8 Feb 2011 16:29:34 -0800 Subject: [PATCH] USB: xhci: fix couple sparse annotations There is no point in casting to (void *) when setting up xhci->ir_set as it only makes us lose __iomem annotation and makes sparse unhappy. OTOH we do need to cast to (void *) when calculating xhci->dba from offset, but since it is IO memory we need to annotate it as such.
