Subject: linux-next: manual merge of the v4l-dvb tree with the 2c tree

Hi Mauro,

Today's linux-next merge of the v4l-dvb tree got a conflict in
drivers/staging/media/go7007/go7007-driver.c between commit bf51a8c5e0b6
("i2c: Ignore return value of i2c_del_adapter()") from the i2c tree and
commit d5d3a7cc127d ("[media] go7007: fix unregister/disconnect
handling") from the v4l-dvb tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
