+Subject: cdc-acm: fix BREAK rx code path adding necessary calls
+
+From: Oliver Neukum <oneukum@suse.com>
+
+commit 08dff274edda54310d6f1cf27b62fddf0f8d146e upstream.
+
+Counting break events is nice but we should actually report them to
+the tty layer.

+
+commit 7180495cb3d0e2a2860d282a468b4146c21da78f upstream.
+
+If tty-device registration fails the driver copy of any Country
+Selection functional descriptor would end up being freed twice; first
+explicitly in the error path and then again in the tty-port destructor.
+
+Drop the first erroneous free that was left when fixing a tty-port
+resource leak.

+commit 93f672804bf2d7a49ef3fd96827ea6290ca1841e upstream.
+
+In host mode port connection status flag is "0" when loading
+the driver. After loading the driver system asserts suspend
+which is handled by "_dwc2_hcd_suspend()" function. Before
+the system suspend the port connection status is "0". As
+result need to check the "port_connect_status" if it is "0",
+then skipping entering to suspend.

+
+commit 72035f4954f0bca2d8c47cf31b3629c42116f5b7 upstream.
+
+init_dma_pools() calls dma_pool_create(...dev->dev) to create dma pool.
+however, dev->dev is actually set after calling init_dma_pools(), which
+effectively makes dma_pool_create(..NULL) and cause crash.
+To fix this issue, init dma only after dev->dev is set.

+Subject: USB: quirks: ignore remote wake-up on Fibocom L850-GL LTE modem
+
+From: Vincent Palatin <vpalatin@chromium.org>
+
+commit 0bd860493f81eb2a46173f6f5e44cc38331c8dbd upstream.
+
+This LTE modem (M.2 card) has a bug in its power management:
+there is some kind of race condition for U3 wake-up between the host and
+the device. The modem firmware sometimes crashes/locks when both events
+happen at the same time and the modem fully drops off the USB bus (and
+sometimes re-enumerates, sometimes just gets stuck until the next
+reboot).
+
+Tested with the modem wired to the XHCI controller on an AMD 3015Ce
+platform. Without the patch, the modem dropped of the USB bus 5 times in
+3 days. With the quirk, it stayed connected for a week while the
+'runtime_suspended_time' counter incremented as excepted.

+commit 6f978a30c9bb12dab1302d0f06951ee290f5e600 upstream.
+
+The MediaTek 0.96 xHCI controller on some platforms does not
+support bulk stream even HCCPARAMS says supporting, due to MaxPSASize
+is set a default value 1 by mistake, here use XHCI_BROKEN_STREAMS
+quirk to fix it.
