   4 Subject: [PATCH] USB: bcma: remove chip id check
   5
   6 I have never seen any bcma device with an USB host core which was not a
   7 SoC, the bcma devices have an USB device core with a different core id.
   8 Some SoC have IDs with 47XX and 53XX in decimal form which would be
   9 rejected by this check. Instead of fixing this check just remove it.
