i2c: s3c2410: fix IRQ check
[ Upstream commit d6840a5e370b7ea4fde16ce2caf431bcc87f9a75 ] 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... Fixes: e0d1ec97853f ("i2c-s3c2410: Change IRQ to be plain integer.")
