From 1bb850a1b7f68b66361e658e334f9fdf8231f17d Mon Sep 17 00:00:00 2001 From: Dan Bogdan Nechita Date: Tue, 23 Feb 2016 11:48:45 +0200 Subject: misc: ad525x_dpot: Fix the enabling of the "otpXen" attributes Currently writing the attributes with "echo" will result in comparing: "enabled\n" with "enabled\0" and attribute is always set to false. Use the sysfs_streq() instead because it treats both NUL and new-line-then-NUL as equivalent string terminations.
