[PATCH -next] v4l2: handle unregister for non-I2C builds

From: Randy Dunlap
Date: Mon May 11 2009 - 12:37:20 EST


From: Randy Dunlap <randy.dunlap@xxxxxxxxxx>

Build fails when CONFIG_I2C=n, so handle that case in the if block:

drivers/built-in.o: In function `v4l2_device_unregister':
(.text+0x157821): undefined reference to `i2c_unregister_device'
