Subject: usb: gadget: f_midi: fix leak on failed to enqueue out requests
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ad0d1a058eac46503edbc510d1ce44c5df8e0c91;p=deliverable%2Flinux.git

usb: gadget: f_midi: fix leak on failed to enqueue out requests

This patch fixes a memory leak that occurs when an endpoint fails to enqueue
the request. If that happens the complete function will never be called, thus
never freeing the request.
