[PATCH 0/2] s390/char: Enable CONTEXT_ANALYSIS

Enable CONTEXT_ANALYSYS for s390/char drivers.

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/char. Add a __must_hold() attribute to
raw3215_make_room() to address the only valid warning.
Then enable CONTEXT_ANALYSIS.

Thanks,
Heiko
