Subject: [PATCH 02/14] drm/panel/ebbg-ft8719: Move to using
 mipi_dsi_dcs_write_seq_multi()

Use mipi_dsi_dcs_write_seq_multi() instead of
mipi_dsi_dcs_write_seq()

Used Coccinelle to do this change. SmPl patch:
@rule_1@
identifier dsi_var;
expression dsi_device;
expression list es;
@@
struct mipi_dsi_device *dsi_var = dsi_device;
+struct mipi_dsi_multi_context dsi_ctx = { .dsi = dsi_var };
<+...
-mipi_dsi_dcs_write_seq(dsi_var,es);
+mipi_dsi_dcs_write_seq_multi(&dsi_ctx,es);
...+>
