Subject: [PATCH] drm/amd/display: fix hdmi_encoded_link_bw definition
Date: Wed, 18 Jan 2023 17:06:27 +0100	[thread overview]
Message-ID: <20230118160722.289840-1-arnd@kernel.org> (raw)

From: Arnd Bergmann <arnd@arndb.de>

Some of the data structures are hidden when CONFIG_DRM_AMD_DC_DCN is
disabled, which leads to a link failure:

drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_dp_capability.c:234:21: error: 'union hdmi_encoded_link_bw' declared inside parameter list will not be visible outside of this definition or declaration [-Werror]

      |                                                                            ^~~~~~~~~~~~~~~~~~~~

There is probably no need to hide the data structure, and removing
the #ifdef makes it build cleanly.
