   4 Subject: [PATCH] dtoverlays: waveshare-panel: Disable new touch controller by
   5  default
   6
   7 Commit e442e5c1ab6b ("arch:arm:boot:dts:overlays: Added waveshare 13.3inch
   8 panel support") added an extra touch controller for the new panels.
   9 On systems with old panels, it ends up spamming the kernel log as that
  10 touch controller isn't there to respond.
