You also need to cherry-pick commit 84855678add8 ("spi: Fix controller unregister order") from spi/for-next onto your topic/spi/reload branch for reloading to work correctly. Alternatively, rebase your topic/spi/reload branch and redo the merge from spi/for-next. (You've merged spi/for-next into your branch on May 14, but the commit was applied by Mark on May 20.)
