ASoC: Ux500: Dispose of device nodes correctly

When of_parse_phandle() is used to find a device node, its
reference count is incremented by the helper. Once we're
finished with them, it's our responsibly to ensure they
are freed in the correct manor.

ALSA: hda - add dock support for Thinkpad T430

I have a Lenovo ThinkPad T430 and an UltraBase Series 3 docking
station.

Without this patch, if I plug my headphones into the jack on the
computer, everything works fine. The computer speakers mute and the
audio is played in the headphones. However, if I plug into the docking
station headphone jack the computer speakers are muted but there is no
audio in the headphones.

ALSA: hdspm - Allow DDS/Varispeed to be set from userspace

The DDS value is the actual physical sample rate. We set it indirectly
when selecting 44100, 48000 and so on via snd_hdspm_hw_params or
hdspm_set_clock_source.

This commit now allows the DDS value to be altered at runtime, thus
speeding up or slowing down the physical sample rate. This is required
for MADI's varispeed that allows for ±12.5% speed adjustment from the
"selected" rate (32kHz, 44100kHz, 48kHz and so on).

ALSA: hdspm - Report external rate in slave mode on PCI MADI

As a follow-up to a97bda7d29d02a2e9c6609d0947b15e55f5200e5, report the
external sample rate as system_sample_rate when in slave mode.

For PCIe MADI cards, the DDS value automatically contains the external
sample rate, but the PCI version needs this manual workaround.

ALSA: sound/isa/opti9xx/miro.c: eliminate possible double free

snd_miro_probe is a static function that is only called twice in the file
that defines it.  At each call site, its argument is freed using
snd_card_free.  Thus, there is no need for snd_miro_probe to call
snd_card_free on its argument on any of its error exit paths.

Because snd_card_free both reads the fields of its argument and kfrees its
argments, the results of the second snd_card_free should be unpredictable.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r@
identifier f,free,a;
parameter list[n] ps;
type T;
expression e;
@@

f(ps,T a,...) {
  ... when any
      when != a = e
  if(...) { ... free(a); ... return ...; }

perf trace: Validate syscall id before growing syscall table

In some cases the ID for a syscall read thru the raw_syscalls tracepoint
is bogus, still needs to be investigated why, but to make the tool more
robust first try to resolve the ID to a name via libaudit and if it
fails, don't grow the table.

perf trace: Check if sample raw_data field is set

Sometimes we're segfaulting because we were expecting that the
perf_sample.raw_data field was set as requested, but in some cases
that needs further investigation, that field can be NULL, leading
to segfaults.

Make the tool more robust by checking that before calling any per event
handlers that may try to use that field.

perf help: Fix --help for builtins

It seems that commit cc5848213329 ("perf help: Remove use of die and
handle errors") caused the problem - it changed the initial value of
'help_format' from HELP_FORMAT_MAN to HELP_FORMAT_NONE.

This broke the --help option for all builtins, that would produce no
output, while 'man perf-top' would work it MANPATH is properly setup.

perf tools: do not flush maps on COMM for perf report

This fixes a long-standing bug caused by the lack of separate COMM and EXEC
record types, which makes "perf report" lose track of symbols when a process
renames itself.

With this fix (suggested by Stephane Eranian), a COMM (rename) no longer
flushes the maps, which is the correct behavior.  An EXEC also no longer
flushes the maps, but this doesn't matter because as new mappings are created
(for the executable and the libraries) the old mappings are automatically
removed.  This is not by accident: the functionality is necessary because DLLs
can be explicitly loaded at any time with dlopen(), possibly on top of existing
text, so "perf report" handles correctly the clobbering of new mappings on top
of old ones.

An alternative patch (which I proposed earlier) would be to introduce a
separate PERF_RECORD_EXEC type, but it is a much larger change (about 300
lines) and is not necessary.
