Hi Greg,
Sudip is absolutely right, the patch he mentioned,
04b2d03a7565 ("spi: Fix double IDR allocation with DT aliases"),
MUST be added too with the mine.
Sudip, thank you for reminding.

From: Kirill Kapranov <kirill.kapranov@xxxxxxxxxxxxxx>
commit 1a4327fbf4554d5b78d75b19a13d40d6de220159 upstream.
On systems where some controllers get a dynamic ID assigned and some have
a fixed number (e.g. from ACPI tables), the current implementation might
run into an IDR collision: in case of a fixed bus number is gotten by a
driver (but not marked busy in IDR tree) and a driver with dynamic bus
number gets the same ID and predictably fails.
Fix this by means of checking-in fixed IDsin IDR as far as dynamic ones
at the moment of the controller registration.
Fixes: 9b61e302210e (spi: Pick spi bus number from Linux idr or spi alias)
