[PATCH 5.4 48/78] usb: musb: dma: Correct parameter passed to IRQ handler

From: Greg Kroah-Hartman
Date: Tue Jan 14 2020 - 05:19:51 EST


From: Paul Cercueil <paul@xxxxxxxxxxxxxxx>

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()")
