[PATCH][2.6] Fix error path in Video4Linux dpc7146 driver

[Michael Hunold]

Hi,

this patch fixes an error path in my dpc7146 Video4Linux driver.

The I2C adapter wasn't de-registered correctly in case the video card 
wasn't found. When the I2C subsystem tried to speak with the dangling 
I2C adapter later on, usually an oops happened.

Please apply.

Regards
Michael Hunold.
