I think we need to fix that problem instead of working around it. So mmc_request_fn already has a null check, it was just missing on mmc_init_request.
I could move `blk_cleanup_queue(q)` above `q->queuedata = NULL` and the lock. So that would mean cherry-picking https://lore.kernel.org/patchwork/patch/856512/ and then a patch with moving blk_cleanup_queue. Should I do that instead? Thanks, Raul
