There is no possible for platform_get_irq() to return 0 and the return value of platform_get_irq() is more sensible to show the error reason.
And there is no need to call the netdev_err() function directly to print a custom message when handling an error from platform_get_irq() function as it is going to display an appropriate error message in case of a failure.
