[PATCH v2 1/2] drm/msm/dp: don't touch DP subconnector property in eDP case

[Dmitry Baryshkov]

From: Abel Vesa <abel.v...@linaro.org>

In case of the eDP connection there is no subconnetor and as such no
subconnector property. Put drm_dp_set_subconnector_property() calls
under the !is_edp condition.

Fixes: bfcc3d8f94f4 ("drm/msm/dp: support setting the DP subconnector type")
