Alexey Khoroshilov df065b373f [media] adv7180: free an interrupt on failure paths in init_device()
There is request_irq() in init_device(), but the interrupt is not removed

Lars-Peter Clausen e246c3332d [media] adv7180: Add support for power down
The adv7180 has a low power mode in which the analog and the digital processing
section are shut down. Implement the s_power callback to let bridge drivers put
the part into low power mode when not needed.

Lars-Peter Clausen 0c25534d45 [media] adv7180: Use threaded IRQ instead of IRQ + workqueue
The proper way to handle IRQs that need to be able to sleep in their IRQ handler
is to use a threaded IRQ.

Lars-Peter Clausen 7933c177fa [media] adv7180: Remove duplicated probe error message
The device driver core already prints out a very similar message when a driver
fails to probe. No need to print one in the driver itself.

Add subdev video ops for ADV7180 video decoder.  This makes decoder usable on
the soc-camera drivers.

Federico Vaga 9f3b935bfd [media] adv7180: remove {query/g_/s_}ctrl
All drivers which use this subdevice use also the control framework.
The v4l2_subdev_core_ops operations {query/g_/s_}ctrl are useless because
device drivers will inherit controls from this subdevice.

Greg Kroah-Hartman 4c62e9764a Drivers: media: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.
