Subject: [PATCH 1/8] powerpc/pseries: fix creation of loop in device node property list
Date: Wed, 14 Aug 2013 22:23:45 -0700 [thread overview]
Message-ID: <1376544232-24936-2-git-send-email-tyreld@linux.vnet.ibm.com> (raw)
In-Reply-To: <1376544232-24936-1-git-send-email-tyreld@linux.vnet.ibm.com>
The update_dt_prop helper function fails to set the IN/OUT parameter prop to
NULL after a complete property has been parsed from the work area returned by
the ibm,update-properties rtas function. This results in the property list of
the device node being updated is corrupted and becomes a loop since the same
property structure is used repeatedly.
