warn about these. For example:

build, check your Kconfig settings to make sure the uclass is being built
(CONFIG_MISC in this case).
Another error that can crop up is something like::
spl/dts/dt-device.c:257:38: error: invalid application of ‘sizeof’ to
incomplete type ‘struct sandbox_irq_priv’
257 | u8 _sandbox_irq_priv_irq_sbox[sizeof(struct sandbox_irq_priv)]
| ^~~~~~
This indicates that `struct sandbox_irq_priv` is not defined anywhere. The
solution is to add a DM_HEADER() line, as below, so this is included in the
dt-device.c file::
U_BOOT_DRIVER(sandbox_irq) = {
.name = "sandbox_irq",
.id = UCLASS_IRQ,
.of_match = sandbox_irq_ids,
.ops = &sandbox_irq_ops,
.priv_auto = sizeof(struct sandbox_irq_priv),
DM_HEADER(<asm/irq.h>)
};
Note that there is no dependency checking on the above, so U-Boot will not
regenerate the dt-device.c file when you update the source file (here,
`irq_sandbox.c`). You need to run `make mrproper` first to get a fresh build.
