Subject: [DRM] Fix a regression caused by a typo
Date: Thu,  2 Jul 2015 14:57:19 -0400	[thread overview]
Message-ID: <1435863439-28660-1-git-send-email-szeng@atronixengineering.com> (raw)

From: Shixin Zeng <zeng.shixin@gmail.com>

The length of each EDID block is EDID_LENGTH, and number of blocks is (1
+ edid->extensions)

This causes wrong EDID to be passed on, and is a regression introduced
by d2ed34362a52 (drm: Introduce helper for replacing blob properties)
