s390/con3215: Add __must_hold() attribute to raw3215_make_room()
Add __must_hold() attribute to raw3215_make_room() in order to let
clang's context analysis know that "get_ccwdev_lock(raw->cdev)" must be
held on function entry. This can also be easily verified when inspecting
the function.
Without this annotation this leads to a valid warning when context
analysis is enabled:
drivers/s390/char/con3215.c:485:9: warning:
expecting spinlock 'raw->cdev->ccwlock' to be held at start of each loop [-Wthread-safety-analysis]
