soc: ti: Use list_first_entry_or_null() at appropriate places
Use list_first_entry_or_null() for first_region() and first_queue_range(). list_first_entry() expects the list is not empty, so first_region() and first_queue_range() never return NULL. Thus use list_first_entry_or_null() instead. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Santosh Shilimkar <ssantosh@kernel.org>
