iio: pressure: zpa2326: Remove always-true check which confuses gcc
With gcc 4.1.2: drivers/iio/pressure/zpa2326.c: In function ‘zpa2326_wait_oneshot_completion’: drivers/iio/pressure/zpa2326.c:868: warning: ‘ret’ may be used uninitialized in this function When testing for "timeout < 0", timeout is already guaranteed to be strict negative, so the branch is always taken, and ret is thus always initialized. But (some version of) gcc is not smart enough to notice. Remove the check to fix this. As there is no other code in between assigning the error codes and returning them, the error codes can be returned immediately, and the intermediate variable can be dropped. Drop the "else" to please checkpatch.
