+Subject: [PATCH v3 2/6] usb: xhci: add Broadcom specific fake doorbell
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This fixes problem with controller seeing devices only in some small
+percentage of cold boots.
+This quirk is also added to the platform data so we can activate it
+when we register our platform driver.
