Subject: 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()")
