Subject: [PATCH] media: usb: fix memory leak in stk_camera_probe
Date: Wed, 14 Jul 2021 11:23:28 +0800 [thread overview]
Message-ID: <20210714032340.504836-1-mudongliangabcd@gmail.com> (raw)
stk_camera_probe mistakenly execute usb_get_intf and increase the
refcount of interface->dev.
Fix this by removing the execution of usb_get_intf.
Reported-by: Dongliang Mu <mudongliangabcd@gmail.com>
Fixes: 0aa77f6c2954 ("[media] move the remaining USB drivers to drivers/media/usb")
