Running "scripts/checkpatch.pl" will yell about the above. You're
supposed to write the word "commit" before the git hash. AKA:
Use functions introduced in commit 966e397e4f603 ("drm/mipi-dsi:
Introduce mipi_dsi_*_write_seq_multi()") and commit f79d6d28d8fe

The subject of your patch has an extra "Subject:" prefix. See:
https://lore.kernel.org/r/485eef24-ddad-466a-a89f-f9f226801bb7@gmail.com
...where you can see "Subject: Subject:". Maybe use "b4" or "patman"
to help you send your patch?

Please adjust the indentation for the followup lines to match. Right
now they line up properly with the old function name, but not the new
one.

Please move the variable declaration above the line "dsi->mode_flags
&= ~MIPI_DSI_MODE_LPM;"
