+Subject: [PATCH] USB: bcma: remove chip id check
+
+I have never seen any bcma device with an USB host core which was not a
+SoC, the bcma devices have an USB device core with a different core id.
+Some SoC have IDs with 47XX and 53XX in decimal form which would be
+rejected by this check. Instead of fixing this check just remove it.
