Revision 5896585512e5156482335e902f7c7393b940da51 authored by Furquan Shaikh on 20 August 2020, 07:52:41 UTC, committed by Alex Deucher on 26 August 2020, 19:13:14 UTC
In `amdgpu_dm_update_backlight_caps()`, there is a local `amdgpu_dm_backlight_caps` object that is filled in by `amdgpu_acpi_get_backlight_caps()`. However, this object is uninitialized before the call and hence the subsequent check for aux_support can fail since it is not initialized by `amdgpu_acpi_get_backlight_caps()` as well. This change initializes this local `amdgpu_dm_backlight_caps` object to 0.
