free_buff_list and rec_buff_list are initialized in the middle of hdpvr_probe(),
but if something bad happens before that, error handling code calls hdpvr_delete(),
which contains iteration over the lists (via hdpvr_free_buffers()).
The patch moves the lists initialization to the beginning and by the way fixes
goto label in error handling of registering videodev.

The image data is laid out a bit more weirdly and thus needs more work to
properly interlace. What we get from hardware is V4L2_FIELD_ALTERNATE, but
since userspace support for it is practically nonexistent, thus we make
V4L2_FIELD_INTERLACED from it so that it's more easily interpreted.

This is a camera with an ov518+ revision 0 bridge + ov7620ae sensor,
which appearently needs different handling then the Trust spacecam 320, which

Hello,
this is a new gspca driver for Syntek STK1135 webcams. The code is completely
new, but register values are based on Syntekdriver (stk11xx) by Nicolas VIVIEN
(http://syntekdriver.sourceforge.net).
Only one webcam type is supported now - vendor 0x174f, device 0x6a31.
It's Asus F5RL laptop flippable webcam with MT9M112.
The camera works better than in Windows - initializes much faster and
provides more resolutions (the sensor can do almost any resolution - just
add it to the stk1135_modes[] - could this feature be somehow used by
applications to avoid SW scaling?).
Autoflip works too - when the camera is flipped around, the image is flipped
automatically.

sd_start() operates on device controls but after the conversion to the
v4l2 control framework in commits 62bba5d and 1bd7d6a controls are
initialized in sd_init_controls() which is called _after_ sd_init():
The change fixes a NULL pointer dereference for Hercules Blog Webcam;
the problem is observable since 3.6:

v4l2-common.c contained a bunch of dv-timings related functions.
Move that to the new v4l2-dv-timings.c which is a more appropriate
place for them.
There aren't many drivers that do HDTV, so it is a good idea to separate
common code related to that into a module of its own.

check_firmware() makes sure firmware is in a device.
It returns zero on success and error code otherwise.
Also it sets down_firmware flag to 1 if downloading occurs.
The only caller poseidon_probe() checks down_firmware flag and
returns 0 without any initialization if it is set.
That looks very strange, so the patch removes down_firmware argument
of check_firmware() and returns error code if check_firmware() fails
in poseidon_probe().
Not tested on real hardware.

The GPIO register caching is the result of wrong assumptions and incomplete
knowledge about the GPIO registers and their functionality.
Today, we know that it is not needed.
It is also limited to a single register and therefore incomplete (newer chips
are using multiple registers).
Instead of extending the caching, get rid of it, because it has no real
benefits and just bloats/complicates the code.

- add definition for GPIO register 0x09 (reading/input)
- extend the information the chip variants that support GPIO registers 0x08/0x09
- rename EM28XX_R08_GPIO to EM2820_R08_GPIO_CTRL

em276x/7x/8x, em2874/174/84
The em25xx/em276x/7x/8x provides 4 GPIO register sets,
each of them consisting of separate read and a write registers.
The same registers are also used by the em2874/174/84.

Remove the silly redefines of pr_err/info/debug.
This improves readability and it also gets rid of a bunch of warnings when
compiling this driver for older kernels using the compatibility media_build
system.

As suggested by Antti, this patch replaces:
https://patchwork.kernel.org/patch/2649861/
The buffer overflow is fixed by reading only the r820t ID register.

As USB/PCI/MEDIA_SUPPORT dependencies can be tristate, we can't
simply make the bool menu to be dependent on it. Everything below
the menu should also depend on it, otherwise, we risk to allow
building them with 'y', while only 'm' would be supported.
So, add an IF just before everything below, in order to avoid
such risks.

current_norm use is deprecated because it is per-devicenode and if you
have more device nodes all dependent on the same video source, then this
no longer works. Just implement g_std instead.

Replace current_norm by g_std. Also initialize the standard to the more
common NTSC-M format (which is also what current_norm used).
