From 6a39ab3b195c125d3fe49d0b0b613c2e1dbbc5a2 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Fri, 1 Nov 2019 11:35:00 +0200 Subject: [PATCH] iio: imu: adis: check ret val for non-zero vs less-than-zero The ADIS library functions return zero on success, and negative values for error. Positive values aren't returned, but we only care about the success value (which is zero). This change is mostly needed so that the compiler won't make any inferences about some about values being potentially un-initialized. This only triggers after making some functions inline, because the compiler can better follow return paths.
