The conversion of the rcar-du driver from the I2C slave encoder to the DRM bridge API left the HDMI encoder's bridge pointer NULL, preventing the bridge from being handled automatically by the DRM core.

Pull more block fixes from Jens Axboe: "As mentioned in the pull the other day, a few more fixes for this round, all related to the bio op changes in this series. Two fixes, and then a cleanup, renaming bio->bi_rw to bio->bi_opf. I wanted to do that change right after or right before -rc1, so that risk of conflict was reduced. I just rebased the series on top of current master, and no new ->bi_rw usage has snuck in" * 'for-linus' of git://git.kernel.dk/linux-block: block: rename bio bi_rw to bi_opf target: iblock_execute_sync_cache() should use bio_set_op_attrs() mm: make __swap_writepage() use bio_set_op_attrs() block/mm: make bdev_ops->rw_page() take a bool for read/write

Since commit 63a4cc24, bio->bi_rw contains flags in the lower portion and the op code in the higher portions. This means that old code that relies on manually setting bi_rw is most likely going to be broken. Instead of letting that brokeness linger, rename the member, to force old and out-of-tree code to break at compile time instead of at runtime. No intended functional changes in this commit.
