Rodrigo Siqueira 8b8a688260 drm/amd/display: Add get_dig_frontend implementation for DCEx ... commit 6bdeff12a96c9a5da95c8d11fefd145eb165e32a upstream. Some old ASICs might not implement/require get_dig_frontend helper; in this scenario, we can have a NULL pointer exception when we try to call it inside vbios disable operation. For example, this situation might happen when using Polaris12 with an eDP panel. This commit avoids this situation by adding a specific get_dig_frontend implementation for DCEx.
