[PATCH 5.13 214/300] i2c: hix5hd2: fix IRQ check

[ 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...
