From: Sergey Shtylyov <s.shtylyov@xxxxxx> [ Upstream commit 661e8a88e8317eb9ffe69c69d6cb4876370fe7e2 ] Iff platform_get_irq() returns 0 for the main IRQ, the driver's probe() method will return 0 early (as if the method's call was successful). Let's consider IRQ0 valid for simplicity -- devm_request_irq() can always override that decision...
