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:
