Subject: [PATCH v2 00/22] media: i2c: ds90ub9xx: Error handling, UB9702
 improvements

Hi,

This series has two main parts: 1) add error handling all around, and 2)
update the drivers according to latest (mostly non-public) information
from TI.

The "Update UB9702 init sequences" patch basically rewrites the init
sequence from scratch, and to make that patch easier to read, the
previous patch first removes the current init sequence. In the final
version these two patches need to be squashed together.

 Tomi
