Subject: staging: iio/ad7291: fix error code in ad7291_probe()
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit b70e19c222a64018d308ebc80333575aff9f4e51 upstream.
We should be returning a negative error code instead of success here.
This would have been detected by GCC, except that the "ret" variable was
initialized with a bogus value to disable GCC's uninitialized variable
warnings. I've cleaned that up, as well.
