If it's too difficult to get the imx219 csi-2 transmitter into the
LP-11 state on power on, perhaps the csi-2 receiver can be a little
more lenient on the transmitter and make the LP-11 timeout a warning
instead of error-out.

Can you try the attached change on top of the version 5 patchset?

If that doesn't work then you're just going to have to fix the bug
in imx219.
