[PATCH v2] drm/amd/display: fix struct init in update_bounding_box

From: Raul E Rangel
Date: Wed Aug 28 2019 - 14:38:07 EST


dcn20_resource.c:2636:9: error: missing braces around initializer [-Werror=missing-braces]
struct _vcs_dpi_voltage_scaling_st calculated_states[MAX_CLOCK_LIMIT_STATES] = {0};

Fixes: 7ed4e6352c16f ("drm/amd/display: Add DCN2 HW Sequencer and Resource")

So apparently `{}` is a gcc extension. The C standard requires at least
one expression. So {{0}} is correct. I got a lint error about {{0}}
needing a space, so i use `{ {0} }`.

Changes in v2:
- Use { {0} } instead of {}
