Commit Message

First of all, remove duplicate message that platform_get_irq()
does already print. Second, correct the error message when unable
to register a handler, which is broken in two ways:
1) the misleading 'get' vs. 'register';
2) missing '\n' at the end.

(Yes, for the curious ones, the dev_*() cases do not require '\n'
and issue it automatically, but it's better to have them explicit)

Fix all this here.

Fixes: 1882e769362b ("gpio: stmpe: Simplify with dev_err_probe()")
