There are inconsistencies inside the driver too on multi-line
comments even without fixing the ones introduced on this series,
as, on several places, multi-line comments are correct:
drivers/media/platform/vsp1/vsp1_bru.c:/*
drivers/media/platform/vsp1/vsp1_bru.c- * The BRU can't perform format conversion, all sink and source formats must be
drivers/media/platform/vsp1/vsp1_bru.c- * identical. We pick the format on the first sink pad (pad 0) and propagate it
drivers/media/platform/vsp1/vsp1_bru.c- * to all other pads.
drivers/media/platform/vsp1/vsp1_bru.c- */
drivers/media/platform/vsp1/vsp1_dl.c:/*
drivers/media/platform/vsp1/vsp1_dl.c- * Initialize a display list body object and allocate DMA memory for the body
drivers/media/platform/vsp1/vsp1_dl.c- * data. The display list body object is expected to have been initialized to
drivers/media/platform/vsp1/vsp1_dl.c- * 0 when allocated.
drivers/media/platform/vsp1/vsp1_dl.c- */
...
I'll address the ones only the CodingStyle violation introduced by this
series. I'll leave for the vsp1 maintainers/developers.
Btw, there are several kernel-doc tags that use just:
/*
...
*/
instead of:
/**
...
*/
I suggest you to add the files/headers with kernel-doc markups on
a Documentation/media/v4l-drivers/vsp1.rst file, to be created.
This way, you can validate that such documentation is correct,
and produce an auto-generated documentation for this driver.

Mauro
