From: Shuah Khan <skhan@xxxxxxxxxxxxxxxxxxx> [ Upstream commit f861d36e021e1ac4a0a2a1f6411d623809975d63 ] rtsx_usb_probe() doesn't call usb_set_intfdata() to null out the interface pointer when probe fails. This leaves a stale pointer. Noticed the missing usb_set_intfdata() while debugging an unrelated invalid DMA mapping problem. Fix it with a call to usb_set_intfdata(..., NULL).
