We had set the i2c clientdata to &flash->subdev_led[LM3560_LED1]
after call lm3560_subdev_init(flash, LM3560_LED1, "lm3560-led1"),
but the container_of() in lm3560_remove() return the wrong pointer
to flash.(should be container_of(subdev, struct lm3560_flash,
subdev_led[LM3560_LED_MAX-1])
This patch fix to set i2c clientdata to flash so we can get flash
from clientdata directly.

This is similar to the Terratec H7. It works with the same az6007 firmware as
the former, however the drx-k firmware of the H7 will NOT work. Hence use
a different firmware name. The firmware does not need to exist as the one in
the eeprom is just fine as long as the h7 one doesn't get loaded, but maybe
some day someone wants to load it (the one from the h5 would work too).
Also since the config entry is now different anyway disable support for rc.
AFAIK the Technisat remote (TS35) is RC5 and the code (which a code comment
claims doesn't work anyway) only would handle NEC hence it's pointless creating
a device and polling it if we already know it can't work.
CI is untested.

Originally based on idea found on
http://www.linuxtv.org/wiki/index.php/TechniSat_CableStar_Combo_HD_CI claiming
only id needs to be added (but failed to mention it only worked because the
driver couldn't find the h7 drx-k firmware...).

This patch adds ioctl helpers to the V4L2 mem-to-mem API, so we can avoid
several ioctl handlers in the mem-to-mem video node drivers that are simply
a pass-through to the v4l2_m2m_* calls. These helpers will only be useful
for drivers that use same mutex for both OUTPUT and CAPTURE queue, which
is the case for all currently in tree v4l2 m2m drivers. In order to use
the helpers the drivers are required to use struct v4l2_fh.
