[PATCH 0/2] scsi: zfcp: Enable CONTEXT_ANALYSIS

[Heiko Carstens <hca@linux.ibm.com>]

Enable CONTEXT_ANALYSYS for the zfcp driver.

Static code checking for acquiring and releasing locks used to be done
with sparse. That was removed with [1] and replaced with a clang based
approach [2]. The new approach requires that each subsystem needs to be
explicitly enabled for checking.

Do that for drivers/s390/scsi. Add a __must_hold() attribute to
zfcp_qdio_sbal_get() to address the only valid warning. Then enable
CONTEXT_ANALYSIS, similar to other patches for drivers/s390 I'm currently
working on.

Thanks,
Heiko
