These are the leftover drivers that didn't have a ->release hook that needed to be updated.

drmm_add_final_kfree(drm, kms);Instead of sprinkling calls to drmm_add_final_kfree() everywhere, wouldn't it be better to pass the parent pointer to drm_dev_init() ?
Would lead to a horrendous monster patch, and even with this splitting there were a few corner cases.
It could be generated by coccinelle, with the semantic patch included in the commit message, so that regenerating it should be possible when merging if conflict arise.
My plan is to add a devm_drm_dev_alloc pattern which combines the usual pattern that most drivers use, see the last patch for all these glorious ideas.
OK I will.
So yeah I hope this will all go away (or mostly at least), but for bisecting I didn't come up with a better idea to get this all off the ground unfortunately.
