Subject: drm/bridge: lvds-codec: Add to_lvds_codec() function
Git-commit: 65c04add090f029abe8255f28448d9a12dd27828
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

Factor out the manual container_of() uses to a common to_lvds_codec()
macro to shorten lines (and provide better type safety, although that
won't matter much in this case).
