[openib-general] [PATCH][13/12] InfiniBand/mthca: initialize mutex earlier

[Roland Dreier]

One more bug that slipped in...


The cap_mask_mutex needs to be initialized before
ib_register_device(), because device registration will call client
init functions that may try to modify the capability mask.
