From 06b113e9f28f8657715919087a3f54b77d1634ed Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Fri, 28 Oct 2016 09:59:38 -0700 Subject: clk: xgene: Don't call __pa on ioremaped address ioremaped addresses are not linearly mapped so the physical address can not be figured out via __pa. More generally, there is no guarantee that backing value of an ioremapped address is a physical address at all. The value here is only used for debugging so just drop the call to __pa on the ioremapped address.
