When applying, I did get a yell from the stricter checkpatch mode:
-:28: CHECK:MACRO_ARG_REUSE: Macro argument reuse 'dsi_ctx' - possible
side-effects?
#28: FILE: drivers/gpu/drm/panel/panel-novatek-nt36523.c:26:
+#define mipi_dsi_dual_dcs_write_seq_multi(dsi_ctx, dsi0, dsi1, cmd,
seq...) \
+ do {
\
+ dsi_ctx.dsi = dsi0;
\
+ mipi_dsi_dcs_write_seq_multi(&dsi_ctx, cmd,
seq); \
+ dsi_ctx.dsi = dsi1;
\
+ mipi_dsi_dcs_write_seq_multi(&dsi_ctx, cmd,
seq); \
} while (0)
That's not new though, so I went ahead and applied the patch anyway. I
think the easiest way to solve it is to just assign "cmd" to a local
variable inside the "do {} while(0)" scope. Pushed to drm-misc-next:
[1/1] drm/panel: novatek-nt36523: transition to mipi_dsi wrapped functions
