Hi Arnd,

After merging the asm-generic tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/usb/musb/musb_host.c: In function 'musb_rx_reinit':
drivers/usb/musb/musb_host.c:577:10: error: 'struct musb' has no member named 'double_buffer_not_ok'
  if (musb->double_buffer_not_ok)
          ^~
drivers/usb/musb/musb_host.c: In function 'musb_ep_program':
drivers/usb/musb/musb_host.c:807:12: error: 'struct musb' has no member named 'double_buffer_not_ok'
    if (musb->double_buffer_not_ok) {
            ^~

Caused by commit

  8312c0cad792 ("usb: musb: remove blackfin port")

I have applied the following patch for today:
