They apply cleanly on Martin's `scsi-queue`, and James' `misc` branches. Both patches make the driver a bit cleaner, and hopefully easier to maintain. Both have been in our CI for quite a while now, running every night. I also gave them a separate regression run just now with I/O and error-injects such as cable pulls and other external error sources. So I am rather confident that they don't break anything for us - apart from that they're straight forward code changes. As always, feedback and further reviews are appreciated :-) Julian Wiedmann (2): zfcp: use list_first_entry_or_null() in zfcp_erp_thread() zfcp: clarify access to erp_action in zfcp_fsf_req_complete() drivers/s390/scsi/zfcp_erp.c | 8 +++----- drivers/s390/scsi/zfcp_fsf.c | 10 ++++++++-- 2 files changed, 11 insertions(+), 7 deletions(-)
