3.13.11-ckt28 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Cristina Opriceana <cristina.opriceana@xxxxxxxxx>
commit 1bdc0293901cbea23c6dc29432e81919d4719844 upstream.
Change return value to 0 if no device is bound since
unsigned int cannot support negative error codes.
Fixes: f18e7a068 ("iio: Return -ENODEV for file operations if the
device has been unregistered")
