[Test Case] I've not seen a failure in practice (well, it's easy to crash 5.0 but, as the commit message notes, that's because it includes an additional patch that happens to "tickle" this. But to regression test, I boot a HiSilicon D06 to a ramdisk and remove the hisi_sas_v3_hw module, which allocates memory as described in the commit message. [Fix] 376991db4b646 driver core: Postpone DMA tear-down until after devres release [Regression Risk] From the stable tree, so in theory would be applied eventually anyway.
