human readable format.

Nice cleanup!

I think these are the only media drivers that would have to be converted,
in case anyone wants to tackle this.

drivers/media/common/saa7146/saa7146_video.c:	      vv->ov_fmt->pixelformat, v4l2_field_names[vv->ov.win.field]);
drivers/media/platform/atmel/atmel-isc-base.c:			 (char *)&pixfmt->pixelformat, (char *)&sd_fmt->fourcc);
drivers/media/platform/sti/delta/delta-debug.c:		 (char *)&f->pixelformat, f->width, f->height,
drivers/media/platform/vsp1/vsp1_drm.c:		cfg->pixelformat, cfg->pitch, &cfg->mem[0], &cfg->mem[1],
