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 2656a9ab upstream. This patch (as1632b) fixes a bug in ehci-hcd. The USB core uses urb->hcpriv to determine whether or not an URB is active; host controller drivers are supposed to set this pointer to a non-NULL value when an URB is queued. However ehci-hcd sets it to NULL for isochronous URBs, which defeats the check in usbcore. In itself this isn't a big deal. But people have recently found that certain sequences of actions will cause the snd-usb-audio driver to reuse URBs without waiting for them to complete. In the absence of proper checking by usbcore, the URBs get added to their endpoint list twice. This leads to list corruption and a system freeze. The patch makes ehci-hcd assign a meaningful value to urb->hcpriv for isochronous URBs. Improving robustness always helps. Signed-off-by:

commit 838f4279 upstream. The ath9k commit 2ef16755 (ath9k: fix signal strength reporting issues) fixed an issue where the reported per-frame signal strength reported to mac80211 was being overwritten with an internal average. The same issue is also present in ath9k_htc. In addition to preventing the driver from overwriting the value, this commit also ensures that the internal average (which is used for ANI) only tracks beacons of the AP that we're connected to.
