Revert "gpiolib: annotate gpio-intialization with __must_check"
This reverts commit 0fdae42d361bbb431ca0ab0efed5126a94821177, which
wasn't really supposed to go in, and causes lots of annoying warnings.
Quoth Andrew:
"Complete brainfart - I meant to drop that patch ages ago."
Quoth Greg:
"Ick, yeah, that patch isn't ok to go in as-is, all of the callers
need to be fixed up first, which is what I thought we had agreed on..."
