For one, the driver device pointer needs to be filled in, or the lirc core
will refuse to load the driver. And we really need to wire up all the
platform_device bits. This has been tested via the lirc sourceforge tree
and verified to work, been sitting there for months, finally getting
around to sending it. :\

This issuses applyed only for Adlink MPG24 board with go7007
& wis2804, all whese changes was tested for continuos
load&restart mode
This is minimal changes needed for start up go7007&wis2804 to work correctly
in 3.4 branch
Changes:
- When go7007 reset device, i2c was not worked (need rewrite GPIO5)
- As wis2804 has i2c_addr=0x00/*really*/, so Need set I2C_CLIENT_TEN flag for validity
- some main nonzero initialization, rewrites with kzalloc instead kmalloc
- STATUS_SHUTDOWN was placed in incorrect place, so if firmware wasn`t loaded, we
failed v4l2_device_unregister with kernel panic (OOPS)
- some new v4l2 style features as call_all(...s_stream...) for using subdev calls
- wis-tw2804.ko module code was incompatible with 3.4 branch in initialization v4l2_subdev parts.
now i2c_get_clientdata(...) contains v4l2_subdev struct instead non standart wis_tw2804 struct
Adds:
- Additional chipset tw2804 controls with: gain,auto gain,inputs[0,1],color kill,chroma gain,gain balances,
for all 4 channels (from tw2804.pdf)
- Power control for each 4 ADC (tw2804) up when s_stream(...,1), down otherwise

This used to be the default if the lock pointer was set, but now that lock is by
default only used for ioctl serialization. Those drivers that already used
core locking have this flag set explicitly, except for some drivers where
it was obvious that there was no need to serialize any file operations other
than ioctl.
The drivers that didn't need this flag were:
drivers/media/radio/dsbr100.c
drivers/media/radio/radio-isa.c
drivers/media/radio/radio-keene.c
drivers/media/radio/radio-miropcm20.c
drivers/media/radio/radio-mr800.c
drivers/media/radio/radio-tea5764.c
drivers/media/radio/radio-timb.c
drivers/media/video/vivi.c
sound/i2c/other/tea575x-tuner.c
The other drivers that use core locking and where it was not immediately
obvious that this flag wasn't needed were changed so that the flag is set
together with a comment that that driver needs work to avoid having to
set that flag. This will often involve taking the core lock in the fops
themselves.
Eventually this flag should go and it should not be used in new drivers.
There are a few reasons why we want to avoid core locking of non-ioctl
fops: in the case of mmap this can lead to a deadlock in rare situations
since when mmap is called the mmap_sem is held and it is possible for
other parts of the code to take that lock as well (copy_from_user()/copy_to_user()
perform a down_read(&mm->mmap_sem) when a page fault occurs).
It is very unlikely that that happens since the core lock serializes all
fops, but the kernel warns about it if lock validation is turned on.
For poll it is also undesirable to take the core lock as that can introduce
increased latency. The same is true for read/write.
While it was possible to make flags or something to turn on/off taking the
core lock for each file operation, in practice it is much simpler to just
not take it at all except for ioctl and leave it to the driver to take the
lock. There are only a handful fops compared to the zillion ioctls we have.
I also wanted to make it obvious which drivers still take the lock for all
fops, so that's why I chose to have drivers set it explicitly.

For control registers a new function needs to be defined so we
can get rid of a layer violation, but that approach must be queued
for the next merge window.

If, in __persistent_ram_init(), the call to
persistent_ram_buffer_init() fails or the call to
persistent_ram_init_ecc() fails then we fail to free the memory we
allocated to 'prz' with kzalloc() - thus leaking it.
To prevent the leaks I consolidated all error exits from the function
at a 'err:' label at the end and made all error cases jump to that
label where we can then make sure we always free 'prz'. This is safe
since all the situations where the code bails out happen before 'prz'
has been stored anywhere and although we'll do a redundant kfree(NULL)
call in the case of kzalloc() itself failing that's OK since kfree()
deals gracefully with NULL pointers and I felt it was more important
to keep all error exits at a single location than to avoid that one
harmless/redundant kfree() on a error path.

right up to the end of the loop.
Also if we don't break out of the loop then we end up past the end of
the array, but with this fix we end up on the last element.

rtsx_transport.c (rtsx_transfer_sglist_adma_partial):
pointer struct scatterlist *sg, which is mapped in dma_map_sg,
is used as an iterator in later transfer operation. It is corrupted and
passed to dma_unmap_sg, thus causing fatal unmap of some erroneous address.
Fix it by duplicating *sg_ptr for iterating.

If, in drivers/staging/media/as102/as102_fw.c::as102_fw_upload(), the call
cmd_buf = kzalloc(MAX_FW_PKT_SIZE, GFP_KERNEL);
should fail and return NULL so that we jump to the 'error:' label,
then we'll end up calling 'release_firmware(firmware);' with
'firmware' still uninitialized - not good.
The easy fix is to just initialize 'firmware' to NULL when we declare
it, since release_firmware() deals gracefully with being passed NULL
pointers.

The just-merged ramster staging driver was dependent on a cleanup patch in
cleancache, so was marked CONFIG_BROKEN until that patch could be
merged. That cleancache patch is now merged (and the correct SHA of the
cleancache patch is 3167760f83 rather than
the one shown in the comment removed in the patch below).
So remove the CONFIG_BROKEN now and the comment that is no longer true...
