   4 Subject: [PATCH 37/47] MIPS: ath79: use correct IRQ number for the OHCI controller on AR7240
   5
   6 The currently assigned IRQ number to the OHCI
   7 controller is incorrect for the AR7240 SoC, and
   8 that leads to the following error message from
   9 the OHCI driver:
  10
  11 ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver
  12 ath79-ohci ath79-ohci: Atheros built-in OHCI controller
  13 ath79-ohci ath79-ohci: new USB bus registered, assigned bus number 1
  14 ath79-ohci ath79-ohci: irq 14, io mem 0x1b000000
  15 hub 1-0:1.0: USB hub found
  16 hub 1-0:1.0: 1 port detected
  17 usb 1-1: new full-speed USB device number 2 using ath79-ohci
  18 ath79-ohci ath79-ohci: Unlink after no-IRQ?  Controller is probably using the wrong IRQ.
  19
  20 Fix this by using the correct IRQ number.
