Subject: drm: meson: dw-hdmi: Use dw_hdmi context to replace hack
Git-commit: 9bc78d6dc818701e47c5ebd0879877a512f039f0
Patch-mainline: v5.9-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
The meson-dw-hdmi driver needs to access its own context from the
.mode_valid() operation. It currently gets it from the dev_private field
of the drm_device retrieved from the connector, which is a hack. Use the
private data passed to the .mode_valid() operation instead.
