Add a check to avoid npd. Can a wording approach (like the following) be a better change description? A null pointer is stored in the local variable “mode” after a call of the function “drm_mode_duplicate” failed. This pointer was used in a subsequent statement where an undesirable dereference will be performed then. Thus add a corresponding return value check. > Cc: stable@xxxxxxxxxxxxxxx Would you like to add the tag “Fixes” accordingly? How do you think about to use a summary phrase like “Prevent null pointer dereference in nv17_tv_get_ld_modes()”? Regards, Markus
