[Suggestion] kernel/irqdesc.c: not checking whether failure occurs for alloc_desc() in early_irq_init().

[Suggestion] kernel/irqdesc.c: not checking whether failure occurs for alloc_desc() in early_irq_init().

[Chen Gang]

Hello Maintainers:

For early_irq_init(), it may be failure (can return an error code), and
for alloc_desc(), also may return 'NULL' when '-ENOMEM'.

But it seems the authors are sure that early_irq_init() are always
success, is it correct ? (or early_irq_init() will never be used ?)

I think, it is better to also check alloc_desc() return value in
early_irq_init().

Please help check when you have time.


Thanks.
