So, call hid_hw_open() in rmi_post_resume() so we make sure that
the
device is alive before we try talking to it.

This fixes RMI device suspend/resume over HID.
-       int ret;
+       int ret = 0;

What's the point?

So that we can use the same out: label at the end of the function that
calls hid_hw_close() to return success. This being said though I just
realized that setting ret will initialize it to 0 anyway, so I guess
this can be dropped

Andy's point was that hid_hw_open() is obviously re-initializing the ret 
before its first use as a return value, so there is no need to initialize 
it at a declaration time.
