iio: industrialio-buffer: Fix iio_buffer_poll return value
[ Upstream commit 1bdc0293901cbea23c6dc29432e81919d4719844 ] 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") Signed-off-by: Cristina Opriceana <cristina.opriceana@gmail.com> Cc: <Stable@vger.kernel.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Sasha Levin <sasha.levin@oracle.com>
