When kernfs_seq_start() fails to obtain an active reference, it
returns ERR_PTR(-ENODEV). kernfs_seq_stop() is then invoked with the
error pointer value; however, it still proceeds to invoke
kernfs_put_active() on the node leading to unbalanced put.
If kernfs_seq_stop() is called even after active ref failure, it
should skip invocation of @ops->seq_stop() and put_active.
Unfortunately, this is a bit complicated because active ref failure
isn't the only thing which may fail with ERR_PTR(-ENODEV).
@ops->seq_start/next() may also fail with the error value and
kernfs_seq_stop() doesn't have a way to tell apart those failures.
Work it around by factoring out the active part of kernfs_seq_stop()
into kernfs_seq_stop_active() and invoking it directly if
@ops->seq_start/next() fail with ERR_PTR(-ENODEV) and updating
kernfs_seq_stop() to skip kernfs_seq_stop_active() on
ERR_PTR(-ENODEV). This is a bit nasty but ensures that the active put
is skipped iff get_active failed in kernfs_seq_start().
tj: This was originally committed as d92d2e6bd72b but got reverted by
683bb2761fbf along with other kernfs self removal patches.
However, this one is an independent fix and shouldn't have been
reverted together. Reinstate the change. Sorry about the mess.

The body of i2c_parent_is_i2c_adapter() is currently guarded by
I2C_MUX. It should be CONFIG_I2C_MUX instead.
Among potentially other problems, this resulted in i2c_lock_adapter()
only locking I2C mux child adapters, and not the parent adapter. In
turn, this could allow inter-mingling of mux child selection and I2C
transactions, which could result in I2C transactions being directed to
the wrong I2C bus, and possibly even switching between busses in the
middle of a transaction.
One concrete issue caused by this bug was corrupted HDMI EDID reads
during boot on the NVIDIA Tegra Seaboard system, although this only
became apparent in recent linux-next, when the boot timing was changed
just enough to trigger the race condition.

The trace buffer has a descriptor pointer that goes back to the trace
array. But it was never assigned. Luckily, nothing uses it (yet), but
it will in the future.
Although nothing currently uses this, if any of the new features get
backported to older kernels, and because this is such a simple change,
I'm marking it for stable too.

replace interruptible_sleep_on_timeout with a non-racy version. This
patch instead just adds a private implementation of the function, now
named oss_broken_sleep_on, and changes over the remaining users in
sound/oss/ so we can remove the global interface.

The use of interruptible_sleep_on_timeout in the dmasound driver
is questionable and we want to kill off all sleep_on variants.
This replaces the calls with wait_event_interruptible_timeout
where possible, to wait for a particular event instead of blocking
in a racy way. In the sq_write function, the easiest solution is
an open-coded prepare_to_wait loop.

We want to remove all sleep_on variants from the kernel because they are
racy. In case of the pinnacle driver, we can replace
interruptible_sleep_on_timeout with wait_event_interruptible_timeout
by changing the meaning of a few flags used in the driver so they
are cleared at wakeup time, which is a somewhat more appropriate
way to do the same, although probably still racy.

Previously the custom GPIO header for the S3C24xx would in turn
bring in the custom pin control implementation from
<plat/gpio-cfg.h>. This is not good as it mixes up two
subsystems and makes the dependencies hard to track. Make
the dependency explicit by explicitly including the pin
control header where needed.

Currently we do a read, a dummy write and a final read to fetch
the error code. The value from the final read is taken.
This is not the recommended way and leads to corrupted/lost ESR
values.
Intel(c) 64 and IA-32 Architectures Software Developer's Manual,
Combined Volumes 1, 2ABC, 3ABC, Section 10.5.3 states:
Before attempt to read from the ESR, software should first
write to it. (The value written does not affect the values read
subsequently; only zero may be written in x2APIC mode.) This
write clears any previously logged errors and updates the ESR
with any errors detected since the last write to the ESR.
This write also rearms the APIC error interrupt triggering
mechanism.
This patch removes the first read such that we are conform with
the manual.
On my (very old) Pentium MMX SMP system this patch fixes the
issue that APIC errors:
a) are not always reported and
b) are reported with false error numbers.

On some AIO (All In One) models with the codec alc668
(Vendor ID: 0x10ec0668) on it, when we plug a headphone into the jack,
the system will switch the output to headphone and set the speaker to
automute as well as change the speaker Pin-ctls from 0x40 to 0x00,
this will bring loud noise to the headphone.
I tried to disable the corresponding EAPD, but it did not help to
eliminate the noise.
According to Takashi's suggestion, we use amp operation to replace the
pinctl modification for the automute, this really eliminate the noise.
