Dan Carpenter 40f0170f22 staging: greybus: fix get_channel_from_mode() failure path 
[ Upstream commit 34164202a5 ]

The get_channel_from_mode() function is supposed to return the channel
which matches the mode.  But it has a bug where if it doesn't find a
matching channel then it returns the last channel.  It should return
NULL instead.

Also remove an unnecessary NULL check on "channel".
