If anyone has any objections, please let me know. ------------------ From: Ryan McCann [ Upstream commit 903705111d863ed8ccf73465da77d232fc422ec1 ] Device core dump add block method adds hardware blocks to dumping queue with stack behavior which causes the hardware blocks to be printed in reverse order. Change the addition to dumping queue data structure from "list_add" to "list_add_tail" for FIFO queue behavior.
