Subject: [PATCH 2/3] drm/edid: Fix uninitialized return variable in edid_load()

drivers/gpu/drm/drm_edid_load.c: In function ‘edid_load’:
drivers/gpu/drm/drm_edid_load.c:141: warning: ‘edid’ may be used uninitialized
in this function

In some error cases, edid_load() will return the uninitialized variable.
Initialize it to NULL to fix this.
