Xiaomeng Tong 2e6c86be0e stm: ltdc: fix two incorrect NULL checks on list iterator ... The two bugs are here: if (encoder) { if (bridge && bridge->timings) The list iterator value 'encoder/bridge' will *always* be set and non-NULL by drm_for_each_encoder()/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, use a new variable '*_iter' as the list iterator, while use the old variable 'encoder/bridge' as a dedicated pointer to point to the found element.
