[PATCH 05/14] drm/panel/samsung-s6d7aa0: Move to using mipi_dsi_dcs_write_seq_multi()
From: Anusha Srivatsa
Date: Thu Feb 06 2025 - 16:08:00 EST
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;
