Cortes" 3.5.7.3 -stable review patch. If anyone has any objections, please let me know. ------------------ From: "Alexis R. Cortes" commit b0e4e606ff6ff26da0f60826e75577b56ba4e463 upstream. This minor patch creates a more stricter conditional for the Z1 sytems for applying the Compliance Mode Patch, this to avoid the quirk to be applied to models that contain a "Z1" in their dmi product string but are different from Z1 systems. This patch should be backported to stable kernels as old as 3.2, that contain the commit 71c731a296f1b08a3724bd1b514b64f1bda87a23 "usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware" Signed-off-by: Alexis R.
