Xiaomeng Tong 8d37abe2c0 stm: ltdc: fix two incorrect NULL checks on list iterator
commit 2e6c86be0e upstream.

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.
