Subject: [PATCH 3/4] drm/amd/display: Cleanup early return in construct_phy
Date: Thu, 13 Nov 2025 17:33:47 +0100	[thread overview]
Message-ID: <20251113163348.137315-4-timur.kristof@gmail.com> (raw)
In-Reply-To: <20251113163348.137315-1-timur.kristof@gmail.com>

Match pre-existing patterns in the DC code base.
Instead of returning early from the construct_phy() function,
add a label at the end and use goto to jump there.
Additionally, respect the DC logger and let it log the function
even when it returns early.
