a1198ccf9c [media] v4l2-ioctl: fix incorrect error code if VIDIOC_DBG_G/S_REGISTER are unsupported
The ioctls VIDIOC_DBG_S_REGISTER and VIDIOC_DBG_G_REGISTER should return -EINVAL
if the driver didn't implement them. Currently they return -EPERM if called as
non-root user. However, this check should only be done if the driver actually
implemented these ioctls. Otherwise, just return -EINVAL as we do with all
unimplemented ioctls.

This bug make the v4l2-compliance test suite fail.

e530a5e3cf [media] gspca_sonixj: Probe sensor type independent of bridge type
Looking at the windows inf file, for usb ids with a sensor type where probing
is needed to determine the type (for example ov7630 or soi768), this is
needed for all bridge variants with a usb id indicating this sensor type.

So do the probing to determine the actual sensor type for types where the
usb-id info is not 100% deterministic, independent of the bridge type.

If you look through the list of currently active usb ids in sonixj, this
effectively only changes the code path for 0c45:60fe (sn9c105 + ov7630) and
0c45:612e (sn9c110 + ov7630), which according to the inf file can have a
soi768 instead of a ov7630 just like the sn9c120 + ov7630 models where we
already probe for a soi7630.

The main reason for this code change is to keep the code paths as bridge
variant independent as possible, so that we don't need a lot of special
per bridge cases, as we enable more usb-ids in the future.

This change makes the 0c45:60fe code path identical to the successfully
tested 0c45:613e, so also make sonixj the default driver for 0c45:60fe.

4944e27d85 [media] gspca_sonixj: Enable more usb ids when sn9c102 gets compiled too
Both we and the windows driver make no sensor specific differences
(with some exceptions) for different sonixj bridge types. Thus if a
sn9c105 bridge has been successfully tested with a sensor, the same
sensor can be successfully used with a sn9c120 bridge too.

Using this knowledge we can move over most usb-ids too the sonixj
driver when both are compiled.

so there is no need to check for both in dev_poll. The check in

d642de2ed4 [media] gspca_main: Set memory type to GSPCA_MEMORY_NO on buffer release
Before this patch we were not setting the memory type to GSPCA_MEMORY_NO
when the buffers were released by the app doing a reqbufs 0. Nor would
the memory type be set to GSPCA_MEMORY_NO on device close, as capture_file
already is NULL on device close because of the reqbufs 0. This caused the
following problem:
-app1 does reqbufs USERPTR for 4 buffers
-app1 does reqbufs USERPTR for 0 buffers
-app2 tries to do reqbufs MMAP for 4 buffers
 fails because gspca_dev->memory still is USERPTR

Fixing this also allows an app to switch memory type's by unrequesting
the buffers and re-requesting them of a different type.

This patch also moves the setting of gspca_dev->frsz and gscpa_dev->memory
to after alloc_frame succeeding, so that they are not changed when allocating
fails.

27074efa2e [media] gspca_main: Locking fixes 2
Before this patch vidioc_dqbuf is using its own read_lock, where as
other queue related functions use queue_lock. This means that dqbuf is
accessing several variables in a racy manor. The most important one
being fr_o, which may be changed from underneath dqbuf by vidioc_reqbufs
or vidioc_streamoff. Other variables which it accesses unprotected
are gspca_dev->memory, gspca_dev->streaming and gspca_dev->capt_file.

This patch fixes this by changing vidioc_dqbuf to also use the queue_lock.

The gspca_dev->streaming boolean is protected against multiple access
through gspca_dev->queue_lock everywhere except for 2 places. This patch
fixes this by bringing it under the lock in vidioc_streamoff. And by
removing the check for gspca_dev->streaming in gspca_disconnect,
the destroy_urbs call may be called multiple times (and is protected
by the usb_lock) and calling wake_up_interruptible can also always be done
safely.

f037484337 [media] tda9875: remove duplicate driver
In commit 411674fd18 the tda9875 support was
added to tvaudio. This means that tda9875 is no longer used since mid-2009.

If there are out-of-tree users of this driver, then they can switch to tvaudio
instead.

The original commit message read as follows:

    This change allows bttv to use tvaudio for this device. Since this device
    has the same i2c address as the tda9874 we need to support both in the same
    tvaudio driver. This makes it possible for tvaudio to detect which chip is
    used. Originally the tda9875 was only available in the dedicated tda9875
    driver, but that makes life very hard for bttv since loading tvaudio might
    misdetect a tda9875 as a tda9874.

So there were good reasons for moving the tda9875 code into tvaudio.

2629484288 ACPICA: Fix issues/fault with automatic "serialized" method support
History: This support changes a method to "serialized" on the fly if the
method generates an AE_ALREADY_EXISTS error, indicating the possibility
that it cannot handle reentrancy.

This fix repairs a couple of issues seen in the field, especially on
machines with many cores.

1) Delete method children only upon the exit of the last thread, so
as to not delete objects out from under running threads.

2) Set the "serialized" bit for the method only upon the exit of the
last thread, so as to not cause deadlock when running threads attempt
to exit.

3) Cleanup the use of the AML "MethodFlags" and internal method flags
so that there is no longer any confustion between the two.

672af843ab ACPICA: Debugger: Lock namespace for duration of a namespace dump
Prevents issues if the namespace is changing underneath the
debugger.  Especially temporary nodes, since the debugger displays
these also.

5d3131f5b0 ACPICA: Fix namespace race condition
Fixes a race condition between method execution and namespace
walks that can possibly fault. Problem was apparently introduced
in version 20100528 as a result of a performance optimization
that reduces the number of namespace walks upon method exit
by using the delete_namespace_subtree function instead of the
delete_namespace_by_owner function used previously. Bug is in
the delete_namespace_subtree function.

6ee400aafb net offloading: Do not mask out NETIF_F_HW_VLAN_TX for vlan.
In netif_skb_features() we return only the features that are valid for vlans
if we have a vlan packet.  However, we should not mask out NETIF_F_HW_VLAN_TX
since it enables transmission of vlan tags and is obviously valid.
