[ Upstream commit 8b917cbe38e9b0d002492477a9fc2bfee2412ce4 ]
The bug is here:
if (!encoder) {
The list iterator value 'encoder' 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, use a new variable 'iter' as the list iterator,
while use the original variable 'encoder' as a dedicated pointer
to point to the found element.
