Hello there, Recent gcc development versions say: drivers/staging/media/atomisp/pci/runtime/rmgr/src/rmgr_vbuf.c:275:33: warning: storing the address of local variable ‘h’ in ‘*handle’ [-Wdangling-pointer=] Source code is *handle = &h; but h is a stack local variable, so exporting its address doesn't make any sense. Regards David Binderman
