    Subject[PATCH 5.13 214/300] i2c: hix5hd2: fix IRQ check
    Date
    From: Sergey Shtylyov <s.shtylyov@omp.ru>

    [ Upstream commit f9b459c2ba5edfe247e86b45ad5dea8da542f3ea ]

    Iff platform_get_irq() returns 0, 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...
