Only SMIAPP_ALIGN_DIM() is. I can't see any harm from that, though --- there could be redundant checks in other drivers, too. > sel->r.width = max_t(unsigned int, > sensor->limits[SMIAPP_LIMIT_MIN_X_OUTPUT_SIZE], Do you think it'd be worth adding a note on this change to the list of V4L2 in each kernel version in Documentation/DocBook/media/v4l/compat.xml? -- Kind regards, Sakari Ailus e-mail: sakari.ailus@xxxxxx XMPP: sailus@xxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
