Subject: [PATCH] misc: rtsx: set NULL intfdata when probe fails
Date: Fri, 29 Apr 2022 15:09:13 -0600 [thread overview]
Message-ID: <20220429210913.46804-1-skhan@linuxfoundation.org> (raw)
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).
