213fd22704 Staging: iio: signedness bug 
i2c_smbus_read_byte_data() returns an s32 type.  We need to change
"rate" to signed for the error handling to work.

Also I changed it to propogate the error code instead of just returning
-EINVAL.  Other error codes could be -EAGAIN for example.

d1ae4da731 drivers/staging/iio: call mutex_unlock in error handling code 
Adjust the error handling code so that it benefits from the call to
mutex_unlock at the end of the function.

The semantic match that finds this problem is as follows:

// <smpl>

mutex_lock@p1(E);
