I ran smatch (http://repo.or.cz/w/smatch.git) on it and there are some bugs worth fixing. drivers/input/misc/imon.c +331 free_imon_context(7) error: dereferencing freed memory 'context' Move the debug line earlier. drivers/input/misc/imon.c +1812 imon_probe(216) error: dereferencing undefined: 'context->idev' drivers/input/misc/imon.c +1876 imon_probe(280) error: dereferencing undefined: 'context->touch' The allocation func can return NULL. They probably won't fail in real life, but it will slightly annoy every person checking running smatch over the entire kernel (me). drivers/input/misc/imon.c +1979 imon_probe(383) error: double unlock 'mutex:&context->lock' drivers/input/misc/imon.c +1983 imon_probe(387) error: double unlock 'mutex:&context->lock' It sometimes unlocks both before and after the goto. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
