linux-yocto/4.12: ide:ide-cd: fix kernel panic resulting from missing scsi_req_init
Integrating a backport of upstream commit: ide:ide-cd: fix kernel panic resulting from missing scsi_req_init commit 79d73346ac05bc31 upstream Since we split the scsi_request out of struct request, while the standard prep_rq_fn builds 10 byte cmds, it missed to invoke scsi_req_init() to initialize certain fields of a scsi_request structure (.__cmd[], .cmd, .cmd_len and .sense_len but no other members of struct scsi_request). An example panic on virtual machines (qemu/virtualbox) to boot from IDE cdrom: ...
