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.
