Applied, thanks!
[1/3] dma: add dma_xalloc() and dma_xzalloc()
https://git.pengutronix.de/cgit/barebox/commit/?id=fbf187a7d59e (link may

[2/3] treewide: use dma_xalloc()/dma_xzalloc() where the result isn't checked
https://git.pengutronix.de/cgit/barebox/commit/?id=54aeb3aabe4e (link may
not be stable)
[3/3] dma: let dma_alloc() and dma_zalloc() fail
