I'm using arm-none-eabi-gcc (15:13.2.rel1-2) 13.2.1 20231009.

I would also expect a warning, but none appears. Even when I change
the "caller" to

    if (0)
        cadence_qspi_apb_write_protect_disable(priv->regbase);

there is no warning. However if I remove those two "caller" lines
completely, then I get the warning:

    drivers/spi/cadence_qspi_apb.c:334:13: warning:
'cadence_qspi_apb_write_protect_disable' defined but not used
[-Wunused-function]

I'm compiling with CONFIG_CC_OPTIMIZE_FOR_SIZE and #
CONFIG_OPTIMIZE_INLINING is not set (eg. the default values).

Either way, I am happy to add back an #ifdef around the function definitions.
