Subject: [PATCH] input synaptics-rmi4: stop scanning PDT after blank page
Date: Fri, 7 Mar 2014 18:04:16 -0800 [thread overview]
Message-ID: <1394244256-16950-1-git-send-email-cheiny@synaptics.com> (raw)
When scanning the Page Descriptor Table, the end of the PDT is marked by a
page where the first PDT entry is empty. Stop scanning when we find this
page.
