[PATCH] drm/amd/display: fix undefined struct member reference

[PATCH] drm/amd/display: fix undefined struct member reference

[Arnd Bergmann]

An initialization was added for two optional struct members.  One of
these is always present in the dcn20_resource file, but the other one
depends on CONFIG_DRM_AMD_DC_DSC_SUPPORT and causes a build failure if
that is missing:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn20/dcn20_resource.c:926:14: error: excess elements in struct initializer [-Werror]
   .num_dsc = 5,

Add another #ifdef around the assignment.

Fixes: c3d03c5a196f ("drm/amd/display: Include num_vmid and num_dsc within NV14's resource caps")

Thank you for catching that 😊 On my side I kept that flag enabled all the time, so I didn't realize there was a warning hidden here.

What tree is this reported on?

We dropped this flag whenever building DCN. Sounds like we're missing a 
patch if you're getting this.

So this is a NAK from me for going into amd-staging-drm-next at least.
