Implement g_parm/s_parm ioctls. Those are used to check the current
frame rate (in fps) and to set it to a value. In practice, there are
only 15 possible different speeds, due to chip limits.

A user discovered that the Geniatech x8000 encountered a regression when
the xc3028 power management was introduced. The xc3028 never recovers after
setting the powerdown register, which is probably because the xc3028 reset
GPIO is not properly configured. Since I do not have access to the hardware
and thus cannot determine the correct GPIO configuration, just disable xc3028
power management on this board, which fixes the regression.
Thanks to user "ritec" for reporting the issue and testing the fix.

The introduction of the zl10353 i2c gate control broke support for the
Geniatech board (which is not behind an i2 gate). Add the needed parameter.

Remove the following build warning:
sms-cards.c: In function 'sms_board_event':
sms-cards.c:120: warning: unused variable 'board'
Thanks to Hans Verkuil for pointing this out.
The problem code has been #if 0'd for now, this will likely be
used again in the future, once the event interface is complete.

The iSight sends non-UVC status events through the interrupt endpoint. Those
invalid events are reported to the kernel log, resulting in a log flood.
Only log the events when the UVC_TRACE_STATUS flag is set.

The current GPIO configuration breaks all Hauppauge devices.
The code being removed affects Hauppauge devices only,
and is the cause of the breakage.

Currently, the VIDIOC_S_STD ioctl just returns -EINVAL regardless of
the norm passed. This patch sets cx23885_mpeg_template.tvnorms and
cx23885_mpeg_template.current_norm so that the VIDIOC_S_STD will work.
Thanks to Joseph Yasi for pointing this out, even though this particular
fix was already pushed into a development repository, merge priority of
this changeset has been escalated as a result of Joseph posting this
identical patch.

Fixes stack corruption bug present in dump_regs function of zl10353 and
qt1010 drivers: the buffer buf was one byte smaller than required -
there are 4 chars for address prefix, 16 * 3 chars for dump of 16 eeprom
bytes per line and 1 byte for zero ending the string required, i.e. 53
bytes, but only 52 were provided.
The one byte missing in stack based buffer buf can cause stack
corruption possibly leading to kernel oops, as discovered originally
with af9015 driver (af9015: fix stack corruption bug).

Some mt9v011 webcams report 0x8332 chip version, instead of 0x8243. From
the revision history at the mt9v011 datasheet, it seems that the chip
version has changed from the first release of the chip.
Thanks-to hermann pitton <hermann-pitton@arcor.de> for pointing this to
me, on his tests with a Silvercrest webcam.
