Add a generic file io (read and write) emulator for videobuf2. It uses
MMAP memory type buffers and generic vb2 calls: req_bufs, qbuf and
dqbuf. Video date is being copied from mmap buffers to userspace with
standard copy_to_user() function. To add support for file io the driver
needs to provide an additional callback - read_setup or write_setup. It
should provide the default number of buffers used by emulator and flags.
With these flags one can detemine the style of read() or write()
emulation. By default 'streaming' style is used. With
VB2_FILEIO_READ_ONCE flag one can select 'one shot' mode for read()
emulator. With VB2_FILEIO_WRITE_IMMEDIATE flag one can select immediate
conversion of write calls to qbuf for write() emulator, so the vb2 will
not wait until each buffer is filled completely before queueing it to
the driver.

Videobuf2 is a Video for Linux 2 API-compatible driver framework for
multimedia devices. It acts as an intermediate layer between userspace
applications and device drivers. It also provides low-level, modular
memory management functions for drivers.
Videobuf2 eases driver development, reduces drivers' code size and aids in
proper and consistent implementation of V4L2 API in drivers.
Videobuf2 memory management backend is fully modular. This allows custom
memory management routines for devices and platforms with non-standard
memory management requirements to be plugged in, without changing the
high-level buffer management functions and API.
The framework provides:
- implementations of streaming I/O V4L2 ioctls and file operations
- high-level video buffer, video queue and state management functions
- video buffer memory allocation and management

Multi-planar API is as a backwards-compatible extension of the V4L2 API,
which allows video buffers to consist of one or more planes. Planes are
separate memory buffers; each has its own mapping, backed by usually
separate physical memory buffers.
Many different uses for the multi-planar API are possible, examples
include:
- embedded devices requiring video components to be placed in physically
separate buffers, e.g. for Samsung S3C/S5P SoC series' video codec,
Y and interleaved Cb/Cr components reside in buffers in different
memory banks;
- applications may receive (or choose to store) video data of one video
buffer in separate memory buffers; such data would have to be temporarily
copied together into one buffer before passing it to a V4L2 device;
- applications or drivers may want to pass metadata related to a buffer and
it may not be possible to place it in the same buffer, together with video
data.

The MAC address reading from the EEPROM along with the
LRC-method to check whether its valid.
Support for the IR-receiver of the Technisat USB2 box. The keys of
small, black remote-control are built-in, repeated key behaviour are
simulated.
The i2c-mutex of the dvb-usb-structure is used as a general mutex for
USB requests, as there are 3 threads racing for atomic requests
consisting of multiple usb-requests.
A module option is there which disables the toggling of LEDs by the
driver on certain triggers. Useful when being used in a "dark"
environment.

This patch reduces the number of sequential pointer derefs in
drivers/scsi/scsi_error.c
This has been submitted a number of times over a couple of years. I
believe this version adresses all comments it has gathered over time.
Please apply or reject with a reason.
The benefits are:
- makes the code easier to read. Lots of sequential derefs of the same
pointers is not easy on the eye.
- theoretically at least, just dereferencing the pointers once can
allow the compiler to generally slightly faster code, so in theory
this could also be a micro speed optimization.
- reduces size of object file (tiny effect: on x86-64, in at least one
configuration, the text size decreased from 9439 bytes to 9400)
- removes some pointless (mostly trailing) whitespace.

Remove incorrect Matrox G200eV support that was previously added by
commit e3a1938805
A serious issue with the incorrect G200eV support that reproduces on the
Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login
banner, login prompt, etc) on the console when X is not running and
total lack of text on all of the virtual consoles after X is started.
Any concerns that the incorrect code (upstream since October 2008) has
been successfully used on non-IBM G200eV equipped system(s) appear to be
unwarranted. In addition to the serious/non-intermittent nature of
issues that have been spotted on IBM systems, complete removal of the
incorrect code is clearly supported by the following Matrox (Yannick
Heneault) provided input:
"It impossible that this patch should have work on a system.
The patch only declare the G200eV as a regular G200 which is
not case. Many registers are different, including at least the
PLL programming sequence. If the G200eV is programmed like a
regular G200, it will not display anything."
v1 - Initial patch that removed the incorrect code for _all_
G200eV equipped systems.
v2 - Darrick Wong provided patch that blacklisted the incorrect
code on G200eV equipped IBM systems leaving it enabled on
all G200eV equipped non-IBM systems.
v3 - Same code changes included with v1 plus additional
justification for complete removal of the incorrect code.
