+Subject: arm64: dts: uniphier: Fix property name in PXs3 USB node
+
+From: Kunihiko Hayashi <hayashi.kunihiko@socionext.com>
+
+commit 2508d5efd7a588d07915a762e1731173854525f9 upstream.
+
+The property "snps,usb2_gadget_lpm_disable" is wrong.
+It should be fixed to "snps,usb2-gadget-lpm-disable".

+Subject: USB: core: Don't hold device lock while reading the "descriptors" sysfs file
+
+From: Alan Stern <stern@rowland.harvard.edu>
+
+commit 45bf39f8df7f05efb83b302c65ae3b9bc92b7065 upstream.
+
+Ever since commit 83e83ecb79a8 ("usb: core: get config and string
+descriptors for unauthorized devices") was merged in 2013, there has
+been no mechanism for reallocating the rawdescriptors buffers in
+struct usb_device after the initial enumeration. Before that commit,
+the buffers would be deallocated when a device was deauthorized and
+reallocated when it was authorized and enumerated.
+
+This means that the locking in the read_descriptors() routine is not
+needed, since the buffers it reads will never be reallocated while the
+routine is running. This locking can interfere with user programs
+trying to read a hub's descriptors via sysfs while new child devices
+of the hub are being initialized, since the hub is locked during this
+procedure.
+
+Since the locking in read_descriptors() hasn't been needed for over
+nine years, we can remove it.

+Subject: usb: gadget: u_serial: Add null pointer check in gserial_resume
+
+From: Prashanth K <quic_prashk@quicinc.com>
+
+commit 5ec63fdbca604568890c577753c6f66c5b3ef0b5 upstream.
+
+Consider a case where gserial_disconnect has already cleared
+gser->ioport. And if a wakeup interrupt triggers afterwards,
+gserial_resume gets called, which will lead to accessing of
+gser->ioport and thus causing null pointer dereference.Add
+a null pointer check to prevent this.
+
+Added a static spinlock to prevent gser->ioport from becoming
+null after the newly added check.

+
+commit e4e7b2dc27c4bb877d850eaff69d41410b2f4237 upstream.
+
+As per USB PD specification, 28th bit of fixed supply sink PDO
+represents "higher capability" attribute and not "usb suspend
+supported" attribute. So, this patch removes the usb_suspend_supported
+attribute from sink PDO.
