From e83596b41cb9729837468a1c14de56a5529a2aa6 Mon Sep 17 00:00:00 2001 From: David Daney Date: Wed, 13 Apr 2016 14:26:56 -0700 Subject: [PATCH] pm80xx: Remove bogus address masking in pm8001_ioremap() It is unclear what the original intent of the masking was, but it is clearly incorrect to truncate a physical address before calling ioremap(). On systems where there are valid physical address bits above bit-31 (arm64 for example) the result is an eventual OOPs when initializing the driver. Remove the bogus code to fix it.
