With the introduction of CSI2 support on sh-mobile, the host driver
switched to using v4l2_device_call_until_err() with grp_id == 0 to
call subdev operations on the sensor and the CSI2 subdev. However,
this has broken multi-client set ups like the one on migor, because
that way all operations get called on both clients. To fix this add
a grp_id and set it to the client private context.

clean up,
If allocating stream buffers for one of the primary streams (e.g. YUV)
failed during card probe, the error path clean up would try to manipulate
the yet unitialized IDX stream structures. This caused a BUG due to
unitialized list heads.
Detect that case and ignore the uninitialized IDX stream.

The SET target with --del-set did not work due to using wrongly

Enforce that the second "src/dst" parameter of the set match and SET target
must be "src", because we have access to the source MAC only in the packet.
The previous behaviour, that the type required the second parameter
but actually ignored the value was counter-intuitive and confusing.

When compiling UBIFS with CONFIG_UBIFS_FS_DEBUG not set,
gcc-4.5.2 generates a slew of "warning: statement with no effect"
on references to non-void functions defined as 0.
To avoid these warnings, replace #defines with dummy inline functions.
Artem: massage the patch a bit, also remove the duplicate
'dbg_check_lprops()' prototype.

DMA mode 1 data corruption anomaly on Blackfin systems. This issue is
specific to the Blackfin silicon as the bug appears to be related to the
connection of the musb ip to the bus/dma fabric.
Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105)
DMA mode 1 allows large size transfers to generate a single interrupt
at the end of the entire transfer. The transfer is split up in packets
of length specified in the Maximum Packet Size field for that endpoint.
If the transfer size is not an integer multiple of the Maximum Packet
Size, a short packet will be present at the end of the transfer.
Under certain conditions this packet may be corrupted in the USB FIFO.
Workaround:
Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA
mode 0 to transfer the short packet.
As an example if your transfer size is 33168 bytes and Maximum Packet
Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and
the remainder (33168 mod 512) in DMA mode 0.

Due to the recent changes to musb's glue layers,
we can't compile musb-hdrc as a module - compilation
will break due to undefined symbol musb_debug. In
order to fix that, we need a big re-work of the
debug support on the MUSB driver.
Because that would mean a lot of new code coming
into the -rc series, it's best to defer that to
next merge window and for now just disable module
support for MUSB.
Once we get the refactor of the debugging support
done, we can simply revert this patch and things
will go back to normal again.

This patch fixes severe UBIFS bug: UBIFS oopses when we 'fsync()' an
file on R/O-mounter file-system. We (the UBIFS authors) incorrectly
thought that VFS would not propagate 'fsync()' down to the file-system
if it is read-only, but this is not the case.
It is easy to exploit this bug using the following simple perl script:
use strict;
use File::Sync qw(fsync sync);
die "File path is not specified" if not defined $ARGV[0];
my $path = $ARGV[0];
open FILE, "<", "$path" or die "Cannot open $path: $!";
fsync(\*FILE) or die "cannot fsync $path: $!";
close FILE or die "Cannot close $path: $!";

Many media center remotes have buttons intended for jumping straight to
one type of media browser or another -- commonly, images/photos/pictures,
audio/music, television, and movies. At present, remotes with an images
or photos or pictures button use any number of different keycodes which
sort of maybe fit. I've seen at least KEY_MEDIA, KEY_CAMERA,
KEY_GRAPHICSEDITOR and KEY_PRESENTATION. None of those seem quite right.
In my mind, KEY_MEDIA should be something more like a media center
application launcher (and I'd like to standardize on that for things
like the windows media center button on the mce remotes). KEY_CAMERA is
used in a lot of webcams, and typically means "take a picture now".
KEY_GRAPHICSEDITOR implies an editor, not a browser. KEY_PRESENTATION
might be the closest fit here, if you think "photo slide show", but it
may well be more intended for "run application in full-screen
presentation mode" or to launch something like magicpoint, I dunno.
And thus, I'd like to have a KEY_IMAGES, which matches the HID Usage AL
Image Browser, the meaning of which I think is crystal-clear. I believe
AL Audio Browser is already covered by KEY_AUDIO, and AL Movie Browser
by KEY_VIDEO, so I'm also adding appropriate comments next to those
keys.

The feature flags NETIF_F_TSO and NETIF_F_TSO6 independently enable
TSO for IPv4 and IPv6 respectively. However, the test in
netdev_fix_features() and its predecessor functions was never updated
to check for NETIF_F_TSO6, possibly because it was originally proposed
that TSO for IPv6 would be dependent on both feature flags.
Now that these feature flags can be changed independently from
user-space and we depend on netdev_fix_features() to fix invalid
feature combinations, it's important to disable them both if
scatter-gather is disabled. Also disable NETIF_F_TSO_ECN so
user-space sees all TSO features as disabled.

The extent_io code can take cached pointers into the extent state trees,
and these can make lookups much faster in common operations. The
caching only happens when specific bits are set that prevent merging
and splitting of the extent state.
A help function was added to uncache the state, and it was testing
the same set of conditionals. This can leak in very strange corner
cases where the lock bit goes away unexpectedly.
The uncaching should be unconditional. Once we have a ref on the
extent we should always give it up.

In fs/nfs/super.c::nfs_fs_mount() we test for a NULL 'data':
...
if (data == NULL || mntfh == NULL)
goto out_free_fh;
...
and then further down in the function we test 'data' again:
...
nfs_fscache_get_super_cookie(
s, data ? data->fscache_uniq : NULL, NULL);
...
this second check is just dead code since there is no way 'data' could
possibly be NULL here.
We also rely on a non-NULL 'data' in more than one location between these
two tests, further proving the point that the second test is bogus.
This patch removes the dead code.

on evergreen/ni. Also, properly set vddci on boot up
for ni cards. The vbios only sets the limited clocks
and voltages on boot until the mc ucode is loaded. This
should fix stability problems on some btc cards.

This is needed for setting voltages other than vddc.

Apparently only rv515 asics need the workaround
added in f24d86f1a49505cdea56728b853a5d0a3f8e3d11
(drm/radeon/kms: fix resume regression for some r5xx laptops).

As per Konrad's original patch, the dummy page used
by the gart code and allocated in radeon_gart_init()
was not freed properly in radeon_gart_fini().
At the same time r6xx and newer allocated and freed the
dummy page on their own. So to do Konrad's patch one
better, just remove the allocation and freeing of the
dummy page in the r6xx, 7xx, evergreen, and ni code and
allocate and free in the gart_init/fini() functions for
all asics.
