Xiaomeng Tong 7ef2fb384f gma500: fix an incorrect NULL check on list iterator ... commit bdef417d84 upstream. The bug is here: return crtc; The list iterator value 'crtc' will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the list is empty or no element is found. To fix the bug, return 'crtc' when found, otherwise return NULL.
