[PATCH 3.16 148/245] usb: musb: dma: Correct parameter passed to IRQ handler

From: Paul Cercueil <paul@crapouillou.net>

commit c80d0f4426c7fdc7efd6ae8d8b021dcfc89b4254 upstream.

The IRQ handler was passed a pointer to a struct dma_controller, but the
argument was then casted to a pointer to a struct musb_dma_controller.

Fixes: 427c4f333474 ("usb: struct device - replace bus_id with dev_name(), dev_set_name()")
