Subject: [PATCH] of: fix of_property_read_string
Date: Tue, 7 Apr 2015 18:11:02 +0800	[thread overview]
Message-ID: <1428401462-5907-1-git-send-email-Shengzhou.Liu@freescale.com> (raw)

In of_property_read_string function, strnlen(prop->value, prop->length)
is always less or equal to prop->length, and we should allow the '=='
condition, so let's remove the original unreasonable condition.
