      serial: arc_uart: Fix module alias · d5a12ea7
      Axel Lin authored
      Platform drivers use "platform:" prefix in module alias.
      Also use DRIVER_NAME in MODULE_ALIAS to make module autoloading work.

      tty_port: Fix refcounting leak in tty_port_tty_hangup() · 1d9e689c
      Gianluca Anzolin authored
      The function tty_port_tty_hangup() could leak a reference to the tty_struct:
      
              struct tty_struct *tty = tty_port_tty_get(port);
      
              if (tty && (!check_clocal || !C_CLOCAL(tty))) {
                      tty_hangup(tty);
                      tty_kref_put(tty);
              }
      
      If tty != NULL and the second condition is false we never call tty_kref_put and
      the reference is leaked.
      
      Fix by always calling tty_kref_put() which accepts a NULL argument.
      
      The patch fixes a regression introduced by commit aa27a094.

      serial/mxs-auart: increase time to wait for transmitter to become idle · 079a036f
      Uwe Kleine-König authored
      Without this patch the driver waits ~1 ms for the UART to become idle. At
      115200n8 this time is (theoretically) enough to transfer 11.5 characters
      (= 115200 bits/s / (10 Bits/char) * 1ms). As the mxs-auart has a fifo size
      of 16 characters the clock is gated too early. The problem is worse for
      lower baud rates.
      
      This only happens to really shut down the transmitter in the middle of a
      transfer if /dev/ttyAPPx isn't opened in userspace (e.g. by a getty) but
      was at least once (because the bootloader doesn't disable the transmitter).
      
      So increase the timeout to 20 ms which should be enough for 9600n8, too.
      Moreover skip gating the clock if the timeout is elapsed.

      serial/mxs-auart: fix race condition in interrupt handler · d970d7fe
      Uwe Kleine-König authored
      The handler needs to ack the pending events before actually handling them.
      Otherwise a new event might come in after it it considered non-pending or
      handled and is acked then without being handled. So this event is only
      noticed when the next interrupt happens.
      
      Without this patch an i.MX28 based machine running an rt-patched kernel
      regularly hangs during boot.

      Pull qxl drm fixes from Dave Airlie:
       "Okay as I warned, the qxl driver was running a bit free and loose with
        its ttm object reservations and the new lockdep enabled reservation
        tracking shone a bright light into it, it also with the new
        reservations mutexes hits a possible deadlock during boot.
      
        The first patch is a real fix to render the console correctly as the
        driver used to just drop irq renderering as too hard, this also fixes
        a sleeping while atomic warning.
      
        The other two patches are the big ugly ones that redo how the driver
        allocates objects and reserves them and makes things all work
        properly, I've tested this in a VM, and compared to the current code
        which hits a lockdep warning and the sleep while atomic warning before
        failing.
      
        So sorry this is coming in late, I should have tested qxl before
        merging the mutex code, but I'd rather just fix qxl with this than
        revert the reservations code at this point"

      USB: mos7840: fix race in led handling · 05cf0dec
      Johan Hovold authored
      Fix race in LED handling introduced by commit 0eafe4de ("USB: serial:
      mos7840: add support for MCS7810 devices") which reused the port control
      urb for manipulating the LED without making sure that the urb is not
      already in use. This could lead to the control urb being manipulated
      while in flight.
      
      Fix by adding a dedicated LED urb and ctrlrequest along with a LED-busy
      flag to handle concurrency.
