Since kernel 3.8, the initialization for Stellar (sms1000)
devices are broken.
Those devices have a behaviour different than usual sms1100
and sms2270: they start with one USB ID (devices in cold state),
but after firmware load, they get a different USB ID.
This weren't docummented at the driver. So, the patches that added
support for sms2270 broke it.
Properly documment it, and provide a debug log that allows to
follow all phases of the device initialization:

There is an asymmetry in ttusb_dec_init_usb()-ttusb_init_rc()
and ttusb_dec_exit_usb()-ttusb_dec_exit_rc() in terms of resources
allocated-deallocated. irq_urb and irq_buffer are allocated in
ttusb_dec_init_usb(), while they are deallocated in ttusb_dec_exit_rc().
As a result there is a leak of them in ttusb_dec_probe().
The patch fixes the asymmetry and a leak on a failure path in ttusb_dec_init_usb().
By the way, it
- removes usage of -1 as a custom error code,
- replaces GFP_ATOMIC by GFP_KERNEL in usb_alloc_coherent() in ttusb_dec_init_usb()
as soon as all other memory allocation done with GFP_KERNEL;
- refactors ttusb_dec_boot_dsp() in an equivalent way except for returning 0
instead of 1 if ttusb_dec_boot_dsp() succeed in (!mode) branch.

When the tuner part of the ds3000 driver was split to share code with the m88rs2000 driver, the ts2020 driver used
the frequency divider value from the m88rs2000 driver. However the ds3000 driver requires a different value, and this
resulted in some frequecies being invisible to the tuner. This patch adds back in the value needed for the ds3000 driver
and configured as an option in the dw2102 frontend driver.
It may also apply to su3000 devices, which use the same ds3000 driver, but for now it is only applied to the s660 device.

Reading firmware status register to detect whether firmware is
running or not didn't work 100% reliably. That register was
likely set by firmware itself which means it could not contain
reasonable values until firmware is up and running. Usually it
just worked as some garbage value was returned accidentally but it
appears that in some cases returned garbage value was 0x00 which
was considered "firmware is up and running" by the driver and
firmware loading was skipped leaving device to non-working state.
Fix problem by removing unreliable check and let the driver keep
count whether firmware is loaded or not.

Most DMA engines have limitations regarding the number of DMA segments
(sg-buffers) that they can handle. Videobuffers can easily spread
through hundreds of pages.
In the previous aproach, the pages were allocated individually, this
could led to the creation houndreds of dma segments (sg-buffers) that
could not be handled by some DMA engines.
This patch tries to minimize the number of DMA segments by using
alloc_pages. In the worst case it will behave as before, but most
of the times it will reduce the number of dma segments

Pull block IO fixes from Jens Axboe:
"After merge window, no new stuff this time only a collection of neatly
confined and simple fixes"
* 'for-3.12/core' of git://git.kernel.dk/linux-block:
cfq: explicitly use 64bit divide operation for 64bit arguments
block: Add nr_bios to block_rq_remap tracepoint
If the queue is dying then we only call the rq->end_io callout. This leaves bios setup on the request, because the caller assumes when the blk_execute_rq_nowait/blk_execute_rq call has completed that the rq->bios have been cleaned up.
bio-integrity: Fix use of bs->bio_integrity_pool after free
blkcg: relocate root_blkg setting and clearing
block: Convert kmalloc_node(...GFP_ZERO...) to kzalloc_node(...)
block: trace all devices plug operation
Pull btrfs fixes from Chris Mason:
"These are mostly bug fixes and a two small performance fixes. The
most important of the bunch are Josef's fix for a snapshotting
regression and Mark's update to fix compile problems on arm"
