Subject: drm/udl: Set preferred color depth to 16 bpp
Git-commit: d8177841aa8a5d32767a5a18413c30b40234a4e5
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
The current default color depth of 24 bpp is not even supported by
the driver. Being the native format for communicating with the adapter,
16 bpp is the correct choice.
