[PATCH 46/49] drm/amd/display: Add callback for update_soc_for_wm_a for dcn303

Alex Deucher alexander.deucher at amd.com
Wed May 12 17:30:50 UTC 2021


From: Aurabindo Pillai <aurabindo.pillai at amd.com>

[Why&How]
Absense of this callback causes null pointer dereference.
Add the corresponding callback in dcn303 resources.

Fixes: 8ea9608379 ("drm/amd/display: fix dcn3+ bw validation soc param update sequence")
