[PATCH 0/2] drm/i915/dsi: Fix error on DSI video mode command

In CI system, the Broxton with DSI display throws an error message with

*ERROR* Video mode command 0x00000041 send failed.

In order to get rid of the error message, we should send SHUTDOWN before
MIPI_SEQ_DISPLAY_OFF for VBT's higher than v3.

If we end up sending two or more MIPI commands that are the same, an error
message is thrown. The patch suggests to replace this error message with a
debug message as it is not that severe failure. With this change the CI
system is not flip flopping due to error message in dmesg log.
