Re: [PATCH v2] spi: ppc4xx: handle irq_of_parse_and_map() errors

...

Zero and negative number is not a valid IRQ for in-kernel code and the irq_of_parse_and_map() function returns zero on error. So this check for valid IRQs should only accept values > 0.

Changes in v2:

• added Cc stable line;
• added Fixes line.

The Cc stable seems clearly disproportionate here.

I wonder a bit about such a feedback (according to a commit from 2009-09-23).

Greg Kroah-Hartman configured a patch email bot in other ways.
