From 1a135d1ab5e3122ab2a50cbbdb9cb1504c1f421f Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 8 Jun 2012 09:54:32 +0300 Subject: iio: frequency: adf4350: using an uninitialized variable GCC complains that we use an uninitialized variable if the user passes an invalid parameter to adf4350_read(). I decided that we should return -EINVAL instead in that case. However, when I looked up at adf4350_write() it returned -ENODEV for that condition. In the end, I decided the -EINVAL was the right thing and I change adf4350_write() to match.
