From f7ef7e3e506023f826c1ee60b7e59b985316e180 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 21 Apr 2015 12:21:53 +0300 Subject: [PATCH] efi: efivar_create_sysfs_entry() should return negative error codes It's not very normal to return 1 on failure and 0 on success. There isn't a reason for it here, the callers don't care so long as it's non-zero on failure.
