commit dcc01c08 upstream. Before the USB core resets a device, we need to disable the L1 timeout for the roothub, if USB 2.0 Link PM is enabled. Otherwise the port may transition into L1 in between descriptor fetches, before we know if the USB device descriptors changed. LPM will be re-enabled after the full device descriptors are fetched, and we can confirm the device still supports USB 2.0 LPM after the reset. We don't need to wait for the USB device to exit L1 before resetting the device, since the xHCI roothub port diagrams show a transition to the Reset state from any of the Ux states (see Figure 34 in the 2012-08-14 xHCI specification update). This patch should be backported to kernels as old as 3.2, that contain the commit 65580b43 "xHCI: set USB2 hardware LPM". That was the first commit to enable USB 2.0 hardware-driven Link Power Management. Signed-off-by:

commit f875fdbf upstream. Since uhci-hcd, ehci-hcd, and xhci-hcd support runtime PM, the .pm field in their pci_driver structures should be protected by CONFIG_PM rather than CONFIG_PM_SLEEP. The corresponding change has already been made for ohci-hcd. Without this change, controllers won't do runtime suspend if system suspend or hibernation isn't enabled. Signed-off-by:

commit 9d892429 upstream. This patch fixes a build error that occurs when CONFIG_PM is enabled and CONFIG_PM_SLEEP isn't: >> drivers/usb/host/ohci-pci.c:294:10: error: 'usb_hcd_pci_pm_ops' undeclared here (not in a function) .pm = &usb_hcd_pci_pm_ops Since the usb_hcd_pci_pm_ops structure is defined and used when CONFIG_PM is enabled, its declaration should not be protected by CONFIG_PM_SLEEP.

commit e877dd2f upstream.

commit 5bf8fae3 upstream. we never allocate a TRB pool for physical endpoints 0 and 1 so trying to free it (a invalid TRB pool pointer) will lead us in a warning while removing dwc3.ko module. In order to fix the situation, all we have to do is skip dwc3_free_trb_pool() for physical endpoints 0 and 1 just as we while deleting endpoints from the endpoints list. Signed-off-by:

commit 71d9a2b9 upstream. The FT4232H used in the ST Micro Connect Lite has four hi-speed UART ports. The first two ports are reserved for the JTAG interface. We enable by default ports 2 and 3 as UARTs (where port 2 is a conventional RS-232 UART) Signed-off-by:

commit eba0e3c3 upstream. Johan's 'fix use-after-free in TIOCMIWAIT' patchset[1] introduces one bug which can cause kernel hang when opening port. This patch initialized the 'port->delta_msr_wait' waitqueue head to fix the bug which is introduced in 3.9-rc4. [1], http://marc.info/?l=linux-usb&m=136368139627876&w=2Signed-off-by:

commit 71ccb9b0 upstream. Use the port wait queue and make sure to check the serial disconnected flag before accessing private port data after waking up. This is is needed as the private port data (including the wait queue itself) can be gone when waking up after a disconnect. When switching to tty ports, some lifetime assumptions were changed. Specifically, close can now be called before the final tty reference is dropped as part of hangup at device disconnect. Even with the ftdi private-data refcounting this means that the port private data can be freed while a process is sleeping on modem-status changes and thus cannot be relied on to detect disconnects when woken up.

commit e5b33dc9 upstream. Add modem-status-change wait queue to struct usb_serial_port that subdrivers can use to implement TIOCMIWAIT. Currently subdrivers use a private wait queue which may have been released when waking up after device disconnected. Note that we're adding a new wait queue rather than reusing the tty-port one as we do not want to get woken up at hangup (yet). Signed-off-by:

commit 6169b673 upstream. We've seen the broken HDMI *video* output on some machines with GM965, and the debugging session pointed that the culprit is the disabled audio output pins. Toggling these pins dynamically on demand caused flickering of HDMI TV. This patch changes the behavior to keep the pin ON constantly.

commit 9ddf1aeb upstream. For non-snoop mode, we fiddle with the page attributes of CORB/RIRB and the position buffer, but also the ring buffers. The problem is that the current code blindly assumes that the buffer is contiguous. However, the ring buffers may be SG-buffers, thus a wrong vmapped address is passed there, leading to Oops. This patch fixes the handling for SG-buffers. Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=800701Signed-off-by:

commit 1539d4f8 upstream. When recording at 176.2KHz or 192Khz, the device adds a 32-bit length header to the capture packets, which obviously needs to be ignored for recording to work properly. Userspace expected: L0 L1 L2 R0 R1 R2 ...but actually got: R2 L0 L1 L2 R0 R1 Also, the last byte of the length header being interpreted as L0 of the first sample caused spikes every 0.5ms, resulting in a loud 16KHz tone (about the highest 'B' on a piano) being present throughout captures. Tested at all sample rates on an E-Mu 0404USB, and tested for regressions on a generic USB headset. Signed-off-by:

commit 80da2e0d upstream. When a whole class of devices (possibly from a specific vendor, or across multiple vendors) require a quirk, explictly listing all devices in the class make the quirks table unnecessarily large. Fix this by allowing matching devices based on interface information. Signed-off-by:
