Subject: [PATCH] staging: iio: frequency: ad9834: Remove unnecessary
 parentheses

Remove unneeded parentheses around the arguments of ||. This reduces
clutter and code behave in the same way. Change suggested by
checkpatch.pl.

CHECK: Unnecessary parentheses around 'st->devid == ID_AD9833'
CHECK: Unnecessary parentheses around 'st->devid == ID_AD9837'
