Clang warns:
../drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:980:36:
warning: address of 'sink->edid_caps.panel_patch.skip_scdc_overwrite'
will always evaluate to 'true' [-Wpointer-bool-conversion]
if (&sink->edid_caps.panel_patch.skip_scdc_overwrite)
~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~
1 warning generated.
This is probably not what was intended so remove the address of
operator, which matches how skip_scdc_overwrite is handled in the rest
of the driver.
While we're here, drop an extra newline after this if block.

As an aside, I don't see skip_scdc_overwrite assigned a value anywhere,
is this working as intended?
