From 2fdaf3f4f8c718a5023db69e2d391d978e94703e Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sat, 2 May 2015 11:25:48 +0100 Subject: [PATCH] iio:light:ltr501 bug in parameter sanity check. Clearly the intent was to error if the value was not 0 or 1. As implemented we have (A != 0 || A != 1) which is always true as A is never both 0 and 1 at the same time. As the autobuilder suggested, && makes more sense for this error check.
