Subject: [PATCH] Input: da9052_onkey: Convert to managed resources

Use managed resource functions devm_input_allocate_device and
devm_kzalloc. To be compatible with the change, replace various
gotos by direct returns and drop unneeded labels.

I prefer not to mix stategies of managing resources in a single driver.
I.e. either everything is devm* or nothing is.
Yeah, I understand. I guess this is an old patch. You can drop it.

Thanks
Thanks.
