+Subject: ALSA: dummy: Fix PCM format loop in proc output
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 2acf25f13ebe8beb40e97a1bbe76f36277c64f1e upstream.
+
+The loop termination for iterating over all formats should contain
+SNDRV_PCM_FORMAT_LAST, not less than it.

+Subject: brcmfmac: Fix memory leak in brcmf_usbdev_qinit
+
+From: Navid Emamdoost <navid.emamdoost@gmail.com>
+
+commit 4282dc057d750c6a7dd92953564b15c26b54c22c upstream.
+
+In the implementation of brcmf_usbdev_qinit() the allocated memory for
+reqs is leaking if usb_alloc_urb() fails. Release reqs in the error
+handling path.

+Subject: usb: gadget: f_ecm: Use atomic_t to track in-flight request
+
+From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
+
+commit d710562e01c48d59be3f60d58b7a85958b39aeda upstream.
+
+Currently ecm->notify_req is used to flag when a request is in-flight.
+ecm->notify_req is set to NULL and when a request completes it is
+subsequently reset.
+
+This is fundamentally buggy in that the unbind logic of the ECM driver will
+unconditionally free ecm->notify_req leading to a NULL pointer dereference.
