Commit Message

When platform_get_irq() is called, the error message has been printed,
so it need not to call dev_err_probe() to print error.

As the comment of platform_get_irq() says, it returned non-zero value
when it succeeded, and it returned negative value when it failed.

Changes in v2:
- Update the comment, explain the return value of platform_get_irq().
