Cool could you bisect and try to find the commit that broke it ? $ git bisect start $ git bisect good v2.6.21-omap1 $ git bisect bad Should help you. Read git help bisect for more information. When you find the exact commit that broke lcd_2430.c, report here with the commit id. Just a note, if you can't build the bisect point, reset to some points before and try again until you find a commit that builds, do not mark them as bad. -- balbi -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
