2014-03-17serial: efm32: properly namespace location propertyUwe Kleine-König
While reviewing an i2c driver for efm32 that needs a similar property Wolfram Sang pointed out that "location" is a too generic name for something that is efm32 specific. So add an appropriate namespace and fall back to the generic name in case of failure.

2014-03-08serial: 8250: Clean up the locking for -rtIngo Molnar
In -RT the spin_lock_irqsave() does not spin but sleep if the lock is taken. Before that, local_irq_save() is invoked which disables interrupts even on -RT. Therefore local_irq_save() + spin_lock() does not work. In the ->sysrq and oops_in_progress case it is save to trylock the lock i.e. this is what we do now anyway except for ->sysrq where we assume that the lock is already taken. The spin_lock_irqsave() grabs the lock and disables the interrupts on vanilla (the same behavior) and on -RT it won't disable interrupts.

2014-02-28serial: sh-sci: Add missing call to uart_remove_one_port() in failure pathGeert Uytterhoeven
If cpufreq_register_notifier() fails, we have to remove the port added by sci_probe_single(), which is not done by sci_cleanup_single(). Else the serial port stays active from the point of view of the serial subsystem, and it may crash when userspace getty is started, or when the loadable driver module is unloaded. This was introduced by commit 6dae14216c85eea13db7b12c469475c5d30e5499 ("serial: sh-sci: Fix probe error paths").

2014-02-28tty: Set correct tty name in 'active' sysfs attributeHannes Reinecke
The 'active' sysfs attribute should refer to the currently active tty devices the console is running on, not the currently active console. The console structure doesn't refer to any device in sysfs, only the tty the console is running on has. So we need to print out the tty names in 'active', not the console names. There is one special-case, which is tty0. If the console is directed to it, we want 'tty0' to show up in the file, so user-space knows that the messages get forwarded to the active VT. The ->device() callback would resolve tty0, though. Hence, treat it special and don't call into the VT layer to resolve it (plymouth is known to depend on it).

2014-02-28tty: Fix low_latency BUGPeter Hurley
The user-settable knob, low_latency, has been the source of several BUG reports which stem from flush_to_ldisc() running in interrupt context. Since 3.12, which added several sleeping locks (termios_rwsem and buf->lock) to the input processing path, the frequency of these BUG reports has increased. Note that changes in 3.12 did not introduce this regression; sleeping locks were first added to the input processing path with the removal of the BKL from N_TTY in commit a88a69c91256418c5907c2f1f8a0ec0a36f9e6cc, 'n_tty: Fix loss of echoed characters and remove bkl from n_tty' and later in commit 38db89799bdf11625a831c5af33938dcb11908b6, 'tty: throttling race fix'. Since those changes, executing flush_to_ldisc() in interrupt_context (ie, low_latency set), is unsafe. However, since most devices do not validate if the low_latency setting is appropriate for the context (process or interrupt) in which they receive data, some reports are due to misconfiguration. Further, serial dma devices for which dma fails, resort to interrupt receiving as a backup without resetting low_latency. Historically, low_latency was used to force wake-up the reading process rather than wait for the next scheduler tick. The effect was to trim multiple milliseconds of latency from when the process would receive new data. Recent tests [1] have shown that the reading process now receives data with only 10's of microseconds latency without low_latency set. Remove the low_latency rx steering from tty_flip_buffer_push(); however, leave the knob as an optional hint to drivers that can tune their rx fifos and such like. Cleanup stale code comments regarding low_latency.

2014-02-28vt: detect and ignore OSC codes.Adam Borowski
These can be used to send commands consisting of an arbitrary string to the terminal, most often used to set a terminal's window title or to redefine the colour palette. Our console doesn't use OSC, unlike everything else, which can lead to junk being displayed if a process sends such a code unconditionally. The rules for termination follow established practice rather than Ecma-48. Ecma-48 requires the string to use only byte values 0x08..0x0D and 0x20..0x7E, terminated with either ESC \ or 0x9C. This would disallow using 8-bit characters, which are reasonable for example in window titles. A widespread idiom is to terminate with 0x07. The behaviour for other control characters differs between terminal emulators, I followed libvte and xterm: * 0x07 and ESC anything terminate * nothing else terminates, all 8-bit values including 0x9C are considered a part of the string Signed-off-by: Adam Borowski <kilobyte@angband.pl> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

All commits found here are real bug fixes, and are mostly trivial. Most of changes in ASoC are the fixes for enum items due to the wrong API usages, in addition to a few DAPM mutex deadlock and other fixes. In HD-audio, only fixups for HP laptops. Although diffstat shows much, the changes are simple: there are just so many different device entries there" * tag 'sound-3.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: ASoC: sta32x: Fix wrong enum for limiter2 release rate ASoC: da732x: Mark DC offset control registers volatile ALSA: hda/realtek - Add more entry for enable HP mute led ALSA: hda - Add a fixup for HP Folio 13 mute LED ASoC: wm8958-dsp: Fix firmware block loading ASoC: sta32x: Fix cache sync ALSA: hda/realtek - Add more entry for enable HP mute led ASoC: dapm: Add locking to snd_soc_dapm_xxxx_pin functions Input - arizona-haptics: Fix double lock of dapm_mutex ASoC: wm8400: Fix the wrong number of enum items ASoC: isabelle: Fix the wrong number of items in enum ctls ASoC: ad1980: Fix wrong number of items for capture source ASoC: wm8994: Fix the wrong number of enum items ASoC: wm8900: Fix the wrong number of enum items ASoC: wm8770: Fix wrong number of enum items ASoC: sta32x: Fix array access overflow ASoC: dapm: Correct regulator bypass error messages
