i2c: mt65xx: fix IRQ check
[ Upstream commit 58fb7c643d346e2364404554f531cfa6a1a3917c ]
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...
