From: Jerome Kurtz <jrm.kurtz@xxxxxxxxx> When I try to compile with TWL6030_USB=y, TWL4030_USB=y and USB_MUSB_OMAP2PLUS=m, I get the following error: drivers/built-in.o: In function `twl4030_usb_irq': /home/xxx/kernel/linux/drivers/usb/otg/twl4030-usb.c:518: undefined reference to `omap_musb_mailbox' drivers/built-in.o: In function `twl6030_usb_irq': /home/xxx/kernel/linux/drivers/usb/otg/twl6030-usb.c:272: undefined reference to `omap_musb_mailbox' /home/xxx/kernel/linux/drivers/usb/otg/twl6030-usb.c:277: undefined reference to `omap_musb_mailbox' drivers/built-in.o: In function `twl6030_usbotg_irq': /home/xxx/kernel/linux/drivers/usb/otg/twl6030-usb.c:306: undefined reference to `omap_musb_mailbox' drivers/built-in.o: In function `twl4030_usb_phy_init': /home/xxx/kernel/linux/drivers/usb/otg/twl4030-usb.c:540: undefined reference to `omap_musb_mailbox' make: *** [vmlinux] Error 1 To solve this we must add to depends of TWL4030_USB and TWL6030_USB the option : USB_MUSB_OMAP2PLUS as done here.
