Subject: drm/i915: Do not free the passed EDID in intel_connector_update_modes()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ebda95a9965dc6641deacc57ac480e01a378e19b;p=linux-beck.git

drm/i915: Do not free the passed EDID in intel_connector_update_modes()

The caller, not intel_connector_update_modes(), should free the edid. This
improves the reusability of intel_connector_update_modes().
