2016-08-08drm: rcar-du: Link HDMI encoder with bridgeLaurent Pinchart1-0/+1
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. Fix it.

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.

2016-08-07block: rename bio bi_rw to bi_opfJens Axboe51-157/+158
Since commit 63a4cc24867d, 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.
