Subject: [PATCH] powerpc/scom: Create debugfs files using ibm,chip-id if available
Date: Thu, 29 Aug 2013 16:56:59 +1000 [thread overview]
Message-ID: <1377759419.4028.26.camel@pasglop> (raw)
When creating the debugfs scom files, use "ibm,chip-id" as the scom%d
index rather than a simple made up number when possible.
