That example is IMHO the least harmful, as qrwlock must be selected explicitly
by the architecture.
The uses in
drivers/of/base.c
drivers/of/fdt.c
drivers/tty/serial/earlycon.c
drivers/tty/serial/serial_core.c
are more dangerous, and may have bitten people already.
In addition, people may have worked around them in DT, so this series may
actually introduce regressions.
